挤扩支盘桩水平荷载性能有限元分析研究

采用大型软件ANSYS,针对挤扩支盘桩的水平承载特点进行了数值模拟,构造出支盘桩和普通桩的三维模型并进行水平承载的计算比较,结果表明:支盘的设置显著地提高了桩的水平承载力,支盘的角度对桩的承载力产生较大的影响,桩的水平承载力随支盘位置的下降而降低。

Finite element analysis on horizontal load performance of squeezed branch pile

In light of the characters of squeezed branch pile's horizontal load,this paper carries out numerical simulation by ANSYS,builds 3D models of branch pile and common pile,and compares the calculation of their horizontal bearing capacity,which shows that the setting of branch obviously improves the horizontal bearing capacity of pile,the angle of branch has strong influences on the bearing capacity of pile,and the horizontal bearing capacity of pile reduces along with the descend of branch.
