Design Technique Characteristics of Zhenwu Mountain Tunnel

Zhenwu Mountain Tunnel of Yu-Qian Expressway is the most large-scale tunnel with (3-lane) and flat section, which has ever been built up in Chinese southwestern region.The tunnel is located the ecosystem wood area of Chongqing City, where the groundwater is the drinking water source of the city, so the environmental protection requirements are high.Furthermore, with high building density, humanities and natural landscape, the geology circumstance is very complicated and can't be evaded in this region.A lot of scheme comparison and selection works are taken in the design process. According to the project practice,a wast amout of researches and discussions are taken, more difficulties overcome, and the tunnel opened to traffic for one year ahead of time
