| Abstract: | According to the features in the construction process of the tunnel,including the large excavation section,the weak geological conditions,the large percentage of Ⅳ-level and Ⅴ-level surrounding rock,the collapses in the construction process,the surface settlement,the karst caves,the super-large karst caves,the overrunning of the convergence deformation of the weak rock and adopts the respective comprehensive treatment measures,so it can go through the exit long and large shallow bias section and achieve the satisfying results. |
