Abstract: To investigate the influence of new construction method for subway station on the deformation of adjacent pipelines, based on Beijing Road Station of Guiyang Metro Line 3, a 3D model was established using Flac3D software. By simulating and analyzing the construction process, and comparing the simulation results and the in-site monitoring data, the following conclusions were obtained: 1) the settlement deformation of underground pipelines conforms to the general deformation law of strata, and it is closely related to their distance from the center line of the station; 2) the lateral deformation of underground pipelines is related to the excavation span of the station, and the underground pipelines located on both sides of the station have the largest lateral deformation; 3) the change law of the settlement deformation of the underground pipelines with the construction sequence based on the in-site monitoring data is consistent with that based on the simulation results, indicating that the simulation results can provide reference for in-site construction and similar projects.
