Taking the Labor Park Station of Dalian Metro Line 5 as the engineering background, the station is constructed by the PBA reverse construction method. When constructing the station, it is necessary to excavate the guide hole first. In order to study the influence of the group hole effect generated by the PBA construction method on the formation, the model is established by midas-GTS, the simulation of the construction process is carried out to obtain the displacement response of the formation, and the orthogonal test method is used to investigate. The results were analyzed by the method of range analysis. The results show that the operation mode dominates the control of surface settlement during the construction of multi-cavity tunnels; the construction principle of “short-scale footage and diligent support” is reliable; a multi-cavity construction scheme suitable for Dalian is obtained. It is concluded that it is necessary to carry out reasonable theoretical analysis, experimental arrangement and numerical simulation calculation before construction, and it is worthy of promotion in engineering.
