Design of unballasted track bridges on Beijing——Tianjin intercity railway

Beijing-Tianjin intercity railway is the first newly-built passenger dedicated line with operating speed of 350 km/h in our country. During design,new ideas of bridge construction were carried out to ensure the requirements of safety,comfort and stability of the train under high-speed condition. At the same time,concepts of environmental adaptability,service to transportation and comprehensive benefits were observed. On the whole line,long-bridge schemes were adopted and the most advanced technologies of unballasted track were utilized on bridges,the length of which accounts for 87.7 % of the total line. The success of design and construction of the bridges on this rail has accumulated valuable experience for high-speed railway construction on a large scale in the future,and made it a marking,demonstrating,and model project to follow.

Observation and evaluation of bridge settlement in Beijing—Tianjin intercity railway

Specific requirements and methods of settlement monitoring which were used in bridge of unballasted track passenger dedicated line or high-speed railway are introduced systematically,and mathematical model and determinant conditions of settlement were proposed simultaneously,taking Beijing—Tianjin intercity railway as an example.

Study on Urbanization Development Strategy along Wuhan to Xianning Intercity Rail

As the development of＂two-oriented society＂ in Wuhan urban agglomeration, the intercity railway will be an important way of driving the development of urbanization in Wuhan urban agglomeration. Intercity railway shortens the time in traffic between surrounding cities of Wuhan and it brings a lot of people, materials and information. It has also brought opportunities and challenges to the areas along intercity railway. The question is how to seize the development opportunities and coordinate the contradiction between development and environmental protection, and taking a new type urbanization. The paper, studying on the areas along Wuhan to Xianning intercity railway, made a summary of the objective law of urbanization and the influence to the along areas by the intercity railway, meanwhile, had experienced from the developed areas which along the intercity railway both in China and abroad. Then the paper proposed the urbanization development strategy from the aspect of land use, industry, population and transportation on the basis of analysis to be economic base and development conditions of the areas.

Systematic Research and Innovation Practice on New Concepts of Construction for Xiong'an Railway Station

As the first major transport infirastructure in Xiong'an New Area,Beijing-Xiong an Intercity Railway is an important step for China State Railway Group Co.A Ltd.to quickly implement the major strategic plan of CPC Central Committee and the State Council.for the establishment of Xiong'an New Area.Xiong'an Station with double-floor spacious waiting areas and the wonderfiul integration of overpass and station building is the first modern integrated transport hub of this kind in China.Based on the characteristics of Xiong'an Station and in the light of the relevant new theories,methods and technologies,systematic studies and innovative practices on the new concept of building up a"well-connected,filly-integrated,environmen-frindly,passenger-oriented,economically-efficient,uurally-rich,intelligent and convenient"passenger station are carried oul,which achieve good results of application and help accumulate valuable experiences for the construction of passenger stations of Chinese high-speed railways in the new era.

Field acoustic measurements of high-speed train sound along BTIR

In this paper,single-point field measurements of noise radiated from high-speed trains were performed at two sites along Beijing-Tianjin intercity railway(BTIR),aiming at acquiring the realistic acoustic data for validation and verification of physical model and computational prediction.The measurements showed that A-weighted sound pressure levels(SPLs) were between 80 and 87 dBA as trains passed.The maximum noise occurred at the moment when the pantograph arrived,suggesting that pantograph noise was one of the most significant sources.Sound radiated from high-speed trains of BTIR was a typical broadband spectrum with most acoustic power restricted in the range of medium-high frequency from about 400 Hz to 5 kHz.Aerodynamic noise was shown to be the dominant one over other acoustic sources for high-speed trains.
