摘　　要：岩溶及岩溶水等不良地质是控制线路方案的主要工程地质问题。阐述沿江高铁宜昌至涪陵段主要工程地质问题及岩溶发育区对高速铁路工程的影响,并结合宜万铁路岩溶区经验教训,通过该项目岩溶发育区段地质选线案例,总结出山高壁陡的岩溶发育区高速铁路地质选线主要对策与措施。Karst and karst water and other unfavorable geological conditions are the main engineering geological problems to control the route plan.This paper describes the main engineering geological problems of the Yichang—Fuling section of Shanghai—Chongqing—Chengdu high-speed railway and the impact of the karst development area on the high-speed railway project.Combined with the experience and lessons of the karst area of the Yichang—Wanzhou railway,through the geological route selection case of the karst development area of the project,the main countermeasures for the geological route selection of the high-speed railway in the karst development area with high mountains and steep walls are summarized.
