Construction Technology and Safety Risk Control Measures of Deep Foundation Pit Excavation

Deep foundation pit excavation is a basic and key step involved in modern building construction.In order to ensure the construction quality and safety of deep foundation pits,this paper takes a project as an example to analyze deep foundation pit excavation technology,including the nature of this construction project,the main technical measures in the construction of deep foundation pit,and the analysis of the safety risk prevention and control measures.The purpose of this analysis is to provide scientific reference for the construction quality and safety of deep foundation pits.

Research of Risk Identification and Prevention of Underground Pressure Pipelines Damage Caused by External Disturbance

External disturbance is an important cause of underground pressure pipeline damage,which leads to accidents,and it is crucial to study the risk of damage caused by external disturbance and come up with proper prevention and control measures.We reviewed literature on risk identification of underground pressure pipelines damage due to external disturbance was conducted,and a list of risk factors was formed.Based on the list of risk factors,fault tree analysis was carried out on underground pressure pipelines damage caused by external disturbances,and risk prevention and control measures were proposed through the calculation of minimum cut sets,minimum path sets,and structural importance,in hopes of providing reference for the normal operation of underground pressure pipelines.

Security Risk Prevention and Control Deployment for 5G Private Industrial Networks

In this paper,we investigate and analyze the network security risks faced by 5G private industrial networks.Based on current network security architecture and 3GPP requirements and considering the actual application of 5G private industrial networks,a comparative analysis is used to plan and design a private network security construction scheme.The network security construction model,network organization,and key processes of 5G private industrial networks at the current stage are investigated.In addition,the key direction for the next stage of construction is discussed.

Analysis of International Cooperation Management Strategies of Enterprises under the Background of the“Belt and Road”

With the deepening of the“Belt and Road”initiative,Chinese enterprises are facing unprecedented opportunities and challenges for international cooperation.This paper mainly analyzes the current situation,existing problems,and coping strategies of enterprise international cooperation management in the context of the“Belt and Road”.This article expounds on the importance of the“Belt and Road”initiative for international cooperation of enterprises and analyzes the key links of international cooperation management of enterprises from the aspects of internationalization strategy,cross-cultural management,risk prevention and control,and resource integration.Finally,combined with the case,this paper puts forward the management strategies and suggestions that enterprises should adopt in international cooperation,to provide a useful reference for Chinese enterprises in international cooperation in the construction of the“Belt and Road.”

Research on the Risk Management Issues of VAM Agreements in Private Equity Financing

At present,the biggest obstacle that growing enterprises may encounter in their development process is insufficient funds.Private equity financing does not only solve the capital problem of enterprises,but also provide enterprises with professional management concepts and even help growing enterprises to go public in advance.However,high returns must be accompanied by high risks.For example,private equity financing has information asymmetry risks,principal-agent risks,etc.,and these risks make it impossible to maximize the advantages of private equity financing.Therefore,in order to reduce the risks brought by financing,investment and financing parties should choose to sign gambling contracts to reduce the risk.In recent years,the use of VAM agreements has become more in China.However,according to incomplete statistics,less than 30%of VAM agreements are successful,and this result is mainly due to the insufficient depth and breadth of research on VAM agreements.Therefore,this article will comprehensively analyze the problems that need to be paid attention to when signing a gambling agreement by introducing the case of Anda Technology,and the issue of targeted risk prevention will also be discussed in this paper.

The Innovation and Practice in Jakarta-Bandung High Speed Railway Construction

As a flagship project of Sino-Indonesia cooperation within the framework of“the Belt and Road”Initiative(BRI),Jakarta-Bandung High Speed Railway(Jakarta-Bandung HSR)is the first overseas high speed railway entirely implementing China's high speed railway technology with all systems,elements and industrial chain.It marks the success of extensive consultation,joint contribution and shared benefits between China and region states to achieve modernization.By studying the Jakarta-Bandung HSR project,this paper concludes the innovations and successful practices in“going global”of China's railway industry in terms of project organization,engineering construction,railway equipment,operation management,risk prevention and control,etc.Meanwhile,focusing on one of the eight major steps to support high-quality Belt and Road cooperation proposed by President Xi Jinping—building a multidimensional“the Belt and Road”connectivity network,this paper puts forward the specific outlook for China's high speed railway to“go global”and jointly build“the Belt and Road”Initiative from two perspectives of international railway engineering and international scientific and technological cooperation.

A comprehensive multi‐hazard risk assessment model for an urban agglomeration with multiple factors

To assist the Department of Emergency Management in understanding the overall risk characteristics and situation of an urban agglomeration for a reasonable risk prevention and control strategy,this study developed a comprehensive multi-hazard risk assessment model for an urban agglomeration with multiple factors.The proposed model includes disaster probability and disaster loss sub-models.The model evaluated four types of disaster risk in urban agglomerations:natural disasters,accidental disasters,public health incidents,and social security incidents.In addition,a variety of factors were integrated into the model,including the socioeconomic foundation of urban agglomerations,the oligopoly effect of core cities,historical disaster losses,the effect of disaster chains,the ability of disaster prevention and mitigation,and intercity coordinated rescue capabilities.Finally,the risk assessment model was applied to the Beijing-Tianjin-Hebei urban agglomeration.The assessment results were compared to the distribution of the new coronavirus pneumonia epidemic in the target urban agglomeration.The results showed that after analyzing the risk characteristics and evaluating the risk levels,the model not only showed the comprehensive risk levels and distribution of urban agglomerations but also revealed the high-risk areas and the key points of risk prevention and control.More importantly,the results obtained through the model can facilitate the strategic planning of disaster prevention and mitigation for urban agglomerations.
