Abstract
In order to study the deformation law and influencing factors of underground continuous suspended foot walls during the construction process,the finite difference method was used to simulate the deformation during the excavation process of underground continuous suspended foot walls.The feasibility of the numerical simulation was verified by comparing it with theoretical and actual measurement values.The deform-ation law of underground continuous wall during excavation was studied,and it was found that the horizontal deformation of soil decreased with increasing distance.Due to the small aspect ratio of the foundation pit,the impact of the pit angle on the horizontal deformation of the wall is more significant.During the excavation process of the foundation pit,the ratio of maximum deformation to excavation depth is between 0.25%and 1%h.The relationship between maximum deformation and excavation depth and its parameters are provided in the article.In factor analy-sis,it was found that the shoulder width and wall corner embedding depth are inversely proportional to the deformation amount.关键词
