摘　　要：刚-柔性桩复合地基在理论上并不成熟，现行规范中则是强度控制的设计方法，其计算结果与实际出入较大，而基于原状土的切线模量法是较为实用的方法。本文建议采用短桩无垫层，既可以满足承载力和沉降要求，又可以节省成本。The stiffness-flexible pile composite foundation is not mature in theory, the current specification is the strength control design method, which calculation results have larger discrepancy from the actual, and the tangent modulus method is more practical on the basis of undisturbed soil. This article recommends the short pile cushion layer, which not only can meet the requirements of bearing capacity and set lement, but also can save cost.
