摘要
Abstract
Aiming at the typical geological environment of Taiyuan,PLAXIS3D was used to establish numerical models that consider seepage effects and those that do not consider seepage effects.The simulation results of the two were compared with actual monitoring data to verify the reliability of the model that considers seepage effects.On this basis,the deformation characteristics of subway deep foundation pits were studied.The research results show that the horizontal displacement of the retaining pile considering the seepage effect is greater than that of the retaining pile without considering the seepage effect,and is closer to the actual monitoring data;increasing the diameter of the retaining pile can effectively reduce the maximum horizontal displacement of the retaining pile;increasing the thickness of the steel support wall can effectively reduce the maximum horizontal displacement of the retaining pile.关键词
