Abstract
In order to solve the problem when analyzed the numerical value of the excavation deformation of the circular deep foundation pit by the traditional analysis method,the analysis of the horizontal and vertical deformation of the foundation pit was quite different from the actual measurement results.The numerical analysis method of circular deep foundation pit excavation deformation based on finite element analysis was designed and studied.Through the construction of the soil model around the circular deep foundation pit,the simulation of the contact surface and supporting structure of the circular deep foundation pit,the simulation calculation of the circular deep foundation pit excavation process and the deformation analysis of the excavation process based on finite element analysis,a new analytical method was proposed.The experiment further proved that the new analysis method was closer to the actual measurement result than the traditional analysis method.Moreover,the accuracy and precision of numerical analysis were effectively improved,which have great value for the subsequent foundation pit support.关键词
