摘要

针对山区沟谷软基的特点，采取多桩型复合地基进行处理是一个创新。利用有限元仿真手段，并结合现场试验结果，对多桩型复合地基的载荷传递机理进行了分析。分析结果表明，桩身上部存在一定范围的负摩阻力区，最大轴力位于桩顶以下；对比单一桩型复合地基，多桩型复合地基具有更好的基础完整性，传递载荷的能力更强，可以很好地满足特殊地基条件下的承载力和变形要求。

Abstract

Based on the main feature of soft ground in mountainous area

taking the measure of multi-type-pile composite foundation to improve is an innovation. In combination with field test

the load transfer behavior of multi-type-pile composite foundation has been analyzed by use of FEM. The results show that there is a zone of negative friction in pile upside and the maximum axial force is below the top of pile. Compared with single-type-pile composite foundation

the multi-type-pile composite foundation is more whole and possess stronger capacity of load transfer. It can satisfy the requirements of load bearing capacity and deformation under special foundation conditions.
