长短桩复合地基受力性状的有限元分析

Finite element analysis on endurance of long-short-pile composite foundation

采用有限元对长短桩复合地基的受力性状及变形性状进行了分析,计算结果表明,短桩桩身变形模量仅对复合地基的受力性状影响较大,因此,对具体分析工程中的实际地基处理问题,应进行优化设计。

The article analyzes the endurance and deformation behaviors of long-short-pile composite foundation by using finite element, and the calculating result shows that deformation modulus of long-short-pile only has big influences on composite foundation＇s endurance, so man should carry out optimization design to actual foundation treatment in concrete construction.
