摘要：The numerical modelling method was used to analyse the influence of surcharging on underground pipe gallery. By simulating the 200-d surcharging process to observe the settlement, lateral displacement and dissipation of porewater pressure in the preloading area, it is found that the vertical displacement of pipe gallery under the influence of the surcharging near the drainage channel is not more than 10 mm, the lateral displacement is not more than 2.4 cm, and the torsion angle of the pipe gallery is not more than 0.18 degree. Therefore, it can be considered that the surcharging has little influence on the adjacent underground pipe gallery.
