摘　　要：根据有限元分析原理 ,结合工程实例分析了竖向荷载作用下复合材料桩的承载力、荷载传递特性和水泥土桩环侧摩阻力的传递扩散规律 .研究和实践表明 ,复合材料桩具有协同工作、受力均匀合理、沉降变形小、承载力大和造价低等优点 ,具有重要的应用价值 .Composite pile is a new type pile that is manufactured by two or more materials. The bearing capacity and load transfer character of composite pile under the vertical load action has been discussed base on the FEM analysis principle and the construction works .Transfer and spread of the side resistance of cement soil pile ring are analyzed too. It is proved that composite pile has many advantages such as work in coordination with components, small settlement, higher bearing capacity and lower cost, etc.
