摘　　要：运用有限元法系统地分析了刚性桩复合地基中的桩、土荷载分担特性以及基础沉降与垫层特性、桩长、桩距等影响因素之间的关系,还探讨了垫层作用下刚性桩复合地基的有效桩长等问题,所采用的分析方法和一些结论具有工程参考价值。The load sharing ratio of pile to soil in rigid piled composite foundation as well as the settlement of foundation influenced by cushion,pile length and pile spacing,was studied with finite element method.The effective pile length and pile spacing under the action of cushion were also discussed.The analysis method and some conclusions may be a reference for practical engineering.
