Collapse is very common in tunnel construction, which can bring immense casualties and economic losses. The interface of soft and hard rock is the typical location for a tunnel collapse. During Shimenya Tunnel construction, collapse of the section ZK123+370~ZK123+365 of the left tunnel occurred. This paper discusses how distribution of layered rock, attitude of the stratum, hydrogeololgy, and advanced geological prediction can contribute to tunnel collapse. According to collapse mechanisms and in situ collapse conditions, managing and monitoring plans were applied to the tunnel collapse section. To ensure the efficiency and safety of collapse management, convergence displacement and arch crown settlement were measured in the process of tunnel information management. Cause analysis of soft and hard rock tunnel collapse and information management can provide a beneficial reference for avoiding tunnel collapse and developing collapse management programs.
