In this study,the deep foundation pit of Suizhou Huayuecheng project is taken as the research background.The calculated values of pile deformation,pile top displacement and internal support axial force during deep foundation pit excavation are compared with the actual values,as well as the influence of excavation methods on deformation.The results show that there are deviations in the selection of relevant depth,elastic modulus of soil layer and concrete parameters before calculation by software,which leads to'kick'failure.This problem can be solved by reducing the active earth pressure of soil on the supporting structure and increasing the supporting effect of the structure on the soil.
