Abstract
In order to study the horizontal bearing characteristics of expand-base piles under the combined action of horizontal load and external moment(H-M),a model of three pile with expanded bottom in sand under the combined load of horizontal load,H and M in different directions was established with ABAQUS software,and the horizontal ultimate bearing capacity characteristics of single pile were studied.The variation rules of pile top displacement,pile body bending moment and pile body deflection under ultimate load were analyzed,and the reasonableness and accuracy of the numerical analysis are verified by comparing the numerical results with the theoretical calculation results.The results showed that the combined load of exter-nal torque and horizontal force in different directions had different effects on the bearing capacity characteristics of foundation piles.The combination of external torque and horizontal force applied along the Z axis reduced the bearing capacity of single pile.The combination of external torque and horizontal force applied along the X axis increased the bearing capacity of single pile.关键词
