Based on the engineering and geological conditions of the Zhongjie Station of Shenyang Metro Line one, the MIDAS finite element software was used to simulate the four different construction sequences of the tunnel excavation in the PBA construction method, and the same surface loads and fixed Under the condition of constraint and soil parameters, the simulation study shows the changes of arch settlement and surface settlement during the excavation of the tunnel, and the recommended scheme for the excavation sequence under the influence of the group cave effect.
