Study on the Comparison and Selection of the Schemes along the Stream Route and the Cross Ridge Route of Wuxi-Zhenping Expressway in G6911 Trunk Road
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.
