Being a shallow-submersion double-route tunnel, the Jinshazhou Tunnel of the Wu-Guang Passenger-Transportation Railway, whose surrounding rock is complex, is constructed with the bench cut method of NATM. In order to further revise and improve the original design, and effectively guide the following construction, a staged analysis method is applied to analyzing the site monitored data from the construction by the bench cut method, which is proved to help better guide construction and more accurately predict the extremes.
