匀质地基中桩土间力传递的边界元模拟

Boundary Element Method in Analogue for the Process of Forces Transmission between Pile and Soil in Homogeneous Foundation

本文把匀质地基中的桩土之间力传递问题当作两个不同介质相互接触的平面应变问题来研究。用边界元法来描述桩土之间力传递的全过程。对于实际工程中的桩进行模拟计算证明，能较好地反映实际情况，程序精度高，数据准备工作少。对桩的设计和试验研究具有一定的参考价值。

Load transfer in homogeneous foundation is regarded as a two-dimensional plane strain prob-lem of two different media contacting with each other in this paper.The Whole process of load transferbetween pile and soil is described by means of the boundary element method.A lot of analogue calcula-tion on the piles in construction has been done. The method presented in this paper has the followingmerits:high accuracy,simplicity for preparation of input data and realistic reflection of the working con-dition of piles in construction.
