摘要
成自高速铁路城市区域内环境敏感点、建(构)筑物、铁路及公路等交通路网广泛分布,城市发展日新月异,控制因素复杂多样,在保证方案可实施性、与城市规划发展相协调、最大限度降低既有铁路运营风险以及减少构筑物间相互影响等方面是城区选线设计首要考虑的问题,从而选线设计思路、原则也有别于其它区域环境中的铁路选线.结合案例从线路引入径路及敷设方式、车站选址及条件预留、防范降低既有铁路风险以及处理好与构筑物之间关系等四个方面对成自铁路引入枢纽段城区内选线设计进行了梳理分析,总结了一些设计经验和原则,可供类似项目参考.
With the high speed development of the urban area,controlling factors such as environmental sensitive points,buildings,railways,highways are widely distributed in the urban area of Chengdu-Zigong high-speed railway,which are complex and diverse.Feasibility of the scheme,coordination with urban planning and development,minimizing the operation risk of the existing railway,and reducing the interaction with structures are the primary considerations in the urban route selection design.Therefore,the design ideas and principles of urban route selection are different from those of railway route selection in other regions.Combined with the cases,this paper analyzes the route selection design of Chengdu-Zigong high-speed railway in urban area from four aspects:route and laying pattern,station location,preventing and reducing the risk of the existing railway,and relationship within existing structures,and summarizes some design experience and principles,which can be used as a reference for similar projects.
