摘　　要：巫镇高速位于重庆市东北部,地理上与陕西省接壤,是重庆市相邻省份中唯一尚未打通的省际通道,项目区位于大巴山弧形构造与新华夏构造体系的交接复合部位,地质条件极其复杂。为解决此类复杂地形地质条件下的山区高速公路选线问题,采用无人机航拍与常规综合选线手段相结合的方式,根据地形与地质条件、技术标准、工程规模、工程难度及项目可实施性等综合因素反复比选,最终提出安全、经济、环保的路线方案,供类似复杂项目选线参考。Wuxi-Zhenping Expressway is located in the northeastern part of Chongqing and borders Shaanxi Province geographically.It is the only inter-provincial channel in the neighboring provinces of Chongqing that has not yet been opened.The project area is located at the intersection of the Dabashan arcuate structural belt and the Neocathaysian structural system.The geological conditions are extremely complex.In order to solve the problem of expressway route selection as similar complex terrain and geological conditions,by using drone aerial photography and conventional route selection methods.based on comprehensive factors such as terrain and geological conditions,technical standards,project scale,project difficulty,and project feasibility,a safe,economical and environmentally friendly route plan is proposed after repeatedly selection.It is a reference to select routes for similar projects.
