Abstract:  In the process of excavation of underground tunnels, water gushing is often accompanied. In
order to avoid affecting the construction schedule and safety, it is necessary to accurately evaluate the
drainage capacity. In this paper, the drainage capacity of the tunnel is reviewed and calculated, and the
effects of longitudinal slope, steel arch and roughness are considered.
