摘　　要：刚性桩复合地基具有能大幅度提高地基承载力,可有效控制变形等优点,已在工程中广泛应用。刚性桩嵌入基岩时计算模型即发生改变,刚性桩由软弱土中加筋增强体转变为基岩向上延伸的传力体,桩与土形成了土岩组合地基,地基理论模型由复合地基转变为土岩组合地基模型。为此对计算模型、计算方法及设计参数等问题进行讨论。Rigid pile composite foundation has the advantages of greatly improving bearing capacity and effective control deformation,so it is widely used in engineering.When the rigid pile is embedded in the bedrock,the calculation model changes,the rigid pile changes from the reinforcement body in the weak soil to the mass transfer body of the bedrock extension,the pile and soil form-the soil-rock composite ground,and the foundation theory model changes from the composite foundation to the soil-rock composite ground model.The calculation model,calculation method and design parameter problem are discussed in this paper.
