C...The Qinghai-Tibet Railway(QTR) passes through 281 km of sandy land, 11.07 km of which causes serious sand damage to the railway and thus, the control of blown sand is important for the safe operation of the railway. Construction of the railway and sand prevention system greatly changed the blown sand transport of the primary surface. Effective and feasible sand-control measures include stone checkerboard barriers(SCBs), sand fences(SFs), and gravel coverings. This study simulated the embankments, SCBs and SFs of the QTR in a wind tunnel, and analyzed their respective wind profile, sand deposition, and sand-blocking rate(SBR) in conjunction with field data, aiming at studying the influence of Golmud-Lhasa section of the QTR and sand prevention system on blown sand transport. The results of wind tunnel experiments showed that wind speed increased by 67.7%–77.3% at the upwind shoulder of the embankment and decreased by 50.0%–83.3% at upwind foot of embankment. Wind speed decreased by 50.0%–100.0% after passing through the first SF, and 72.2%–100.0% after the first row of stones within the first SCB grid. In the experiment of sand deposition, the higher the wind speed, the lower the SBR of SCB and SF. From field investigation, the amount of sand blocked by the four SFs decreased exponentially and its SBR was about 50.0%. By contrast, SCB could only block lower amounts of sand, but had a higher SBR(96.7%) than SF. Although, results show that SFs and SCBs along the Golmud-Lhasa section of the QTR provide an obvious sand blocking effect, they lead to the deposition of a large amount of sand, which forms artificial dunes and becomes a new source of sand damage.展开更多

The results show that wagon transfer time is the most critical factor among the three subjective factors of wagons turnover time. The FISM based analysis of wagon transfer time show that the wagon turnover time is significantly correlated with transit time with resorting. Among the seven factors of detention time of transit time with resorting, the time of waiting to departing, converging, and waiting to break-up are key factors, while the time of make-up, break-up, arrival and departure are general factors. We carried out one empirical research based on the data of Baoji East Railway Station in 2015. The results of empirical research and FISM are consistent completely.展开更多

However, the annual spring transportation in the special period is still a great challenge to high-speed railway transportation, and this paper analyzes the high-speed railway ticket for spring transportation from the perspective of microeconomics, and then thinks for the solution. This paper specifically analyzes the problem that demand exceeds supply for high-speed railway ticket by using the theories of the demand elasticity of supply and demand and the influence of price on supply and demand, monopoly markets. In addition, opportunity cost, incomplete information and other economic principles are used to think about the theoretical reasons for the difficulty of buying tickets during the spring transportation. I have given my understanding for the two problems owned by China spring transportation, and the corresponding countermeasures and suggestions. For example, speed up the development of substitutes and carry out the mechanism of price fluctuation;In the ticket refunding mechanism, this paper boldly conceives the method to relieve the pressure through a reasonable and scientific ticket refunding mechanism. Finally, this paper starts from the source and find the key point to solve the problem of spring transportation in China by breaking the urban-rural dual structure. Hereafter the final conclusion was drawn: Although there are some problems to cope with the spring transport for the current China high-speed railway, it is believed that in the near future, the difficulty of buying a ticket in spring transportation will no longer hinder the homecoming of wanderers.展开更多

This paper focuses on the industrial organization of China's high-speed railway industry and the applicability of the Anti-Monopoly Law. We intend to answer the following questions: (l) Why is the high-speed railway industry not an industry of natural monopoly? Which segments of the industry have elements of natural monopoly? (2) At the level of corporate organization, what is the legal and economic rationale behind the patterns of China's high-speed railway undertakings evolving from government-affiliated enterprises to special legal person enterprises and then shareholding companies? (3) The applicability of the Anti-Monopoly Law to the high-speed railway industry. Our conclusions from the perspective of competition policy are worth referencing for similar industries such as electric power, telecommunications, and water and gas supply.展开更多

文摘The Qinghai-Tibet Railway(QTR) passes through 281 km of sandy land, 11.07 km of which causes serious sand damage to the railway and thus, the control of blown sand is important for the safe operation of the railway. Construction of the railway and sand prevention system greatly changed the blown sand transport of the primary surface. Effective and feasible sand-control measures include stone checkerboard barriers(SCBs), sand fences(SFs), and gravel coverings. This study simulated the embankments, SCBs and SFs of the QTR in a wind tunnel, and analyzed their respective wind profile, sand deposition, and sand-blocking rate(SBR) in conjunction with field data, aiming at studying the influence of Golmud-Lhasa section of the QTR and sand prevention system on blown sand transport. The results of wind tunnel experiments showed that wind speed increased by 67.7%–77.3% at the upwind shoulder of the embankment and decreased by 50.0%–83.3% at upwind foot of embankment. Wind speed decreased by 50.0%–100.0% after passing through the first SF, and 72.2%–100.0% after the first row of stones within the first SCB grid. In the experiment of sand deposition, the higher the wind speed, the lower the SBR of SCB and SF. From field investigation, the amount of sand blocked by the four SFs decreased exponentially and its SBR was about 50.0%. By contrast, SCB could only block lower amounts of sand, but had a higher SBR(96.7%) than SF. Although, results show that SFs and SCBs along the Golmud-Lhasa section of the QTR provide an obvious sand blocking effect, they lead to the deposition of a large amount of sand, which forms artificial dunes and becomes a new source of sand damage.

文摘To seek a better development in the superior domain of the Journal and build a high influential journal for railway academic and engineering communities,the Editorial Board has decided to narrow the Journal’s publication scope from the general area of transportation covering various transportation systems(railway,highway,air,etc.)to the cutting edges of railway engineering science.With the approval of the State Administration of Press and Publication of China,the title of the Journal shall be changed from Journal of Modern Transportation(CN 51-1739/U,ISSN 2095-087X)to Railway Engineering Science(CN 51-1795/U,ISSN to be issued)with effect from Jan.1,2020.Under the new title,the Journal exclusively focuses on fundamental research progresses in theories and emerging technologies of various rail transit systems,such as high-speed railways,urban rail transit systems,heavy-haul technologies,maglev railways,and hyperloop transportation,aiming to provide a forum for dissemination of innovations in railway research and promote academic exchanges in all aspects of railway engineering science.
文摘The transport of dangerous goods always represents a potential risk to life,human health,property,and environmental protection.For this reason and in order to preserve the lives and health of the participants in the transport process,adequate protection measures must be taken before,during,and after the transport of dangerous goods.Since the railway itself is a recipient of dangerous goods that are essential for its own operation,and is also a carrier of large quantities of various dangerous goods,these measures are of paramount importance.This paper examines,from a point of view of the protection of lives and health of the participants in the transport process and the safe transport of dangerous goods,the conditions of shipment and transport of dangerous goods,the obligations of the participants,and the essential ways for their proper handling.Proper application of safety at work prevents impromptu and indolent attitude in transporting dangerous goods,thus contributing to protection of people lives and health.Finally,this paper includes preventive measures and basic principles for implementation of safety at work in the transport of dangerous goods.
文摘Good equipment management is essential for the day to day management of an enterprise. Targeted at production opera-tion of the railway transportation department of a mining group and aimed at mine railway equipment management, we have estab-lished a management information system for the equipment in the entire process of the life cycle of equipment. The project deals with basic data about equipment, initial management, maintenance, operation and even disposal, based on a C/S and B/S structure. We adopted an object-oriented approach, dealing with software engineering, information engineering, economic and organizational measures. Thus, effective monitoring and control of the operation of railway equipment and its status in the entire process has been achieved.
文摘In recent ten years, the rapid development of China high-speed railway is called "China miracle", and it not only provides great convenience for people's daily life trip, but also greatly promotes the economic development. However, the annual spring transportation in the special period is still a great challenge to high-speed railway transportation, and this paper analyzes the high-speed railway ticket for spring transportation from the perspective of microeconomics, and then thinks for the solution. This paper specifically analyzes the problem that demand exceeds supply for high-speed railway ticket by using the theories of the demand elasticity of supply and demand and the influence of price on supply and demand, monopoly markets. In addition, opportunity cost, incomplete information and other economic principles are used to think about the theoretical reasons for the difficulty of buying tickets during the spring transportation. I have given my understanding for the two problems owned by China spring transportation, and the corresponding countermeasures and suggestions. For example, speed up the development of substitutes and carry out the mechanism of price fluctuation;In the ticket refunding mechanism, this paper boldly conceives the method to relieve the pressure through a reasonable and scientific ticket refunding mechanism. Finally, this paper starts from the source and find the key point to solve the problem of spring transportation in China by breaking the urban-rural dual structure. Hereafter the final conclusion was drawn: Although there are some problems to cope with the spring transport for the current China high-speed railway, it is believed that in the near future, the difficulty of buying a ticket in spring transportation will no longer hinder the homecoming of wanderers.
文摘China's high-speed railway industry achieved dazzling development over the years, but not much research has been devoted to this industry from the perspeetive of competition policy. This paper focuses on the industrial organization of China's high-speed railway industry and the applicability of the Anti-Monopoly Law. We intend to answer the following questions: (l) Why is the high-speed railway industry not an industry of natural monopoly? Which segments of the industry have elements of natural monopoly? (2) At the level of corporate organization, what is the legal and economic rationale behind the patterns of China's high-speed railway undertakings evolving from government-affiliated enterprises to special legal person enterprises and then shareholding companies? (3) The applicability of the Anti-Monopoly Law to the high-speed railway industry. Our conclusions from the perspective of competition policy are worth referencing for similar industries such as electric power, telecommunications, and water and gas supply.
