The Numerical Simulation of Bearing Capacity of Pile-Bucket Foundation under Combined Loading of Up-Pull and Horizontal Force
By using ABAQUS software to conduct numerical simulation and model test of pile-bucket under mono-loading of up-pulling force and horizontal force, then make comparison of both results to testify the accuracy of finite calculation model. Then by numerical simulation to study bearing capacity of pile-bucket foundation under combined loading of up-pull and horizontal force. The result shows the pile-bucket foundation horizontal displacement will increase with the increase of up-pulling force at the limit horizontal load, and the horizontal displacement becomes more obvious as the up-pulling load increasing if providing greater horizontal loading force. Before the up-pulling force reaches the limit, horizontal load will not affect up-pulling displacement; after the up-pulling force reaches the limit, the horizontal load can slightly reduce the up-pulling displacement of pile top. The effect of up-pulling load increase on horizontal displacement is obvious for pile depth in soil at 0~15m, but very tiny for pile body with buried depth over 15m.
