摘　　要：巫镇高速地处渝东北陕鄂渝三省交界的大巴山弧形构造地带,连接重庆奉溪高速和陕西平镇高速,是重庆第一条直连陕西的高速通道。为优化特长隧道和特大桥规模、降低施工难度,方案论证阶段采用“无人机航拍+VR技术”的创新手段辅助精细化选线,剖析了山区高速在沿溪线和越岭线方案选择的关键技术难点,通过综合比选后得到了安全、经济、环保的路线方案。该研究可供山区高速公路科学选线参考。Wuxi-Zhenping Expressway is located in the Daba Mountain arc-structure zone at the junction of the three provinces of northeast Chongqing,Shaanxi,Hubei and Chongqing.It connects Chongqing Fengjie-Wuxi Expressway and Shaanxi PingliZhenping Expressway,and is the first high-speed channel directly connected to Shaanxi in Chongqing.In order to optimize the scale of super-long tunnels and super-large bridges and reduce the difficulty of construction,the innovative means of'UAV aerial photography+VR technology'is used to assist the refined route selection in the scheme demonstration stage.The key technical difficulties in the scheme selection of mountain expressway along the creek route and the mountain route are analyzed.After comprehensive comparison and selection,a safe,economical and environmentally friendly route scheme is obtained.The research can be used as a reference for scientific route selection of mountainous expressways.
