As a common foundation treatment,perfusion occlusal pile is widely used in the field of deep foundation pit.In order to evaluate and predict the vertical bearing capacity of the perfusion pile,combined with the situation of the occlusion pile in the foundation pit project of China Railway Construction South China Headquarters Building,the ABAQUS numerical simulation method was proposed to simulate and analyze the vertical bearing capacity of the perfusion pile.Through the cross connection of concrete pile and reinforced concrete pile,the vertical bearing capacity of cast-in-place pile is analyzed.The results show that,under the action of in-situ stress and the surrounding soil pressure,the main stress of the occlusal pile is distributed in the middle of the reinforced concrete pile and the cross connection.By comparing the bearing capacity of the engineering pile with the predicted value,the reliability of the simulation results of the occlusal cast-in-place pile is tested.
