桩身应力是反映复合地基特性的重要因素，是CFG桩复合地基设计中的重要参数。本文对高速铁路CFG桩复合地基桩筏结构进行了数值模拟，研究了桩间距、褥垫层厚度、桩长对桩身应力的影响。研究表明，桩长是主要因素，而桩间距、褥垫层厚度影响较小。

Pile stress ratio is an important factor to the characteristics of the composite foundation, is an important parameter to design the CFG pile composite foundation.In this article,the CFG pile composite foundation is simulated by Numerical Simulation. such as the pile spacing,cushion thickness and the length of the pile's effect on the pile stress is studied. The reasrearch showed that the length of the pile is a major factor, while the pile spacing,cushion thickness is less affected.
