Overall Design and Technological Innovation of Anqing-Jiujiang High-Speed Railway
The construction conditions of Anqing-Jiujiang High-speed Railway are complex.In the overall design of high-speed railway,it is necessary to introduce the ideas of system engineering design,risk management and life-cycle design.The introduction of the hub scheme requires whole consideration of the comprehensive benefits of the road network and the hub pattern.The comprehensive alignment should take the system optimization as the goal,the project safety as the benchmark,and consider both the technical and economic rationality.The interface design needs to take into account the internal interfaces of the project and the external interfaces of the connected multiple lines with different construction time sequences.Based on the full life cycle of the railway project,the article implements the concept of design for construction,operation and maintenance service,and puts risk management throughout the whole process of survey and design.Aiming at the optimization of system functions,many design innovations have been made in areas such as ballastless tracks,detailed design of bridges,and full section excavation of tunnels,and achieved good social and economic benefits.
