| Abstract: | Through the cause analysis of the landslide and the roof fall for a tunnel, this paper summarized the key control factors of tunnel construction in shallow and soft rock. Through the summary of the tunnel landslide treatment design, it analyzed the core role of the combination advanced support system to form a temporary vault solid crust. The paper provided reference for the prevention and treatment of tunnel collapse, when the tunnel through the soft rock in the future. |
