桩基础有限元法分析

Analysis of Finite Element Method about Pile Base

桩基础应用广泛 ,但计算麻烦 ,传统的计算方法只能考虑单一的土层 ,对于多层土的地基要采用换算的地基系数。本文采用有限元法分析桩基础 ,用弹簧模拟桩侧土对桩的作用 ,可考虑不同的土层 ,适用范围更广 ,计算表明本法具有足够的计算精度。

Pile foundation is used widely,but the calculation is troubled. Traditional calculation only considered single soil layer,it has to adopt equated foundation quotiety for multi soil layer foundation. The paper adopter finite element method to analyze pile foundation,the calculation show that the method has enough calcuation precision.
