【Abstract】 Zhenwushan Tunnel on Chongqing-Guizhou Expressway is the largest highway tunnel with large flat section and three lanes in southwest China. A lot of schemes have been compared during design because the tunnel has a large span andsituates at an unavoidable complicated geologic condition. During design and construction, a lot of researches have been carried out according to the engineering practice. And a lot of difficulties have been overcome so that the tunnel was open to traffic one year ahead of schedule.更多还原
