摘要
杭绍台铁路嵊州—天台区间线路行经天台玄武岩台地,山势起伏较大且局部夹杂深厚硅藻土,城市建设沿沟谷平台密集发展,设计从工程合理、环境共融、服务地方等角度开展综合选线,以充分发挥铁路建设投资效益。从经济据点多线引入站位选址为切入点,结合北段硅藻土玄武岩台地不良地质选线、南段低山丘陵区工程选线优化设计开展分段研究,提出“铁路通达、城规结合、安全可靠、工程合理、环境美化”的复杂山区勘察设计综合选线的思路和方法,解决了空间局促地区交叉铁路车站合理布置、大范围不良地质选线、穿越国家级风景区工程优化等系列技术问题,为类似复杂山区高铁项目提供系统性的选线思路。
With a design speed of 350 km/h,Hangzhou-Shaoxing-Taizhou HSR is China’s first high speed railway project funded by private capital.The Shengzhou-Tiantai section passes through the Tiantaishan Mountains featured by steep terrain,local mixture of deep and thick diatomite as well as intensive urban development along the valley platform.According to the design concept of“railway accessibility,appropriate urban planning,safety and reliability,sound engineering works and environment upgrade”,the paper puts forward the methods of integrated route selection,survey and design in complex mountainous areas.It works to realize reasonable layout of intersecting railway stations in areas with limited space,route selection in large areas with unfavorable geological conditions,project optimization at national scenic spots,as well as a series of other technical challenges,providing systematic solutions for similar high speed railway projects in complex mountainous area.
