Non-linear Finite Element Analysis of Squeezed Branch Pile

In order to analyze the capability of squeezed branch pile under different work conditions and the cooperation mechanism between the pile and soil,non-liner numerical simulation is carried out using ANSYS.Contact interface elements are placed between the pile and soil.It is shown that the squeezed branches take lots of load,and the ratio is related to the load and the elastic modulus of soil.The plastic section of the soil is run-through from bottom to the top.The horizontal displacement of the top soil goes to the pile,but the horizontal displacement of the soil of the bottom goes away from the pile.The squeezed branch will break away from the soil above the squeezed branch when the load is big enough.
