摘要：

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.
