| Abstract: | For the double line tunnel of a section in the rail transit No.3 of certain city, there is a large cross section, a shallow overburden and poor quality of the rock, besides, the top of the tunnel is close to the pile foundation of No.30 and No.31 buildings. Based on abovementioned characteristics, the CRD process and auxiliary process are proposed, and an elastic-plastic finite element method is used to simulate calculation for the process according to its construction steps. It can serve as a basis for the design of construction. |
