摘　　要：刚-柔性桩复合地基设计理论的发展明显地落后于工程实践,基于工程实践成果以及计算机仿真分析结果对刚-柔性桩复合地基设计理论进行了研究,根据不同的基础形式对刚-柔性桩复合地基进行分类,分析了不同型式复合地基的适用性,提出了具体的设计步骤,探讨了承载力与变形等相关问题.此外,还提出了刚-柔性桩复合地基优化设计的建议,并通过工程实例对上述设计理论进行验证.The development of design theory of composite foundation with rigid-flexible piles falls obviously behind the practice. Composite foundation with rigid-flexible piles is classitied into strip foundation, raft foundation and independently foundation, the different design theories such as bearing capacity, deformation are discussed . Specific design procedure is put forward on the basis of engineering practice and the computer simulation result. The paper proposes .some suggestions ＇about design optimization for the composite foundation with rigid-flexible piles. According to preceding theory, the author designs a optimizing project, the result shows that composite foundation with rigid-flexible piles can make rational use of the potentiality of rigid piles, flexible piles and soil bearing capacity, so there will be remarkable economic benefits.
