摘　　要：由刚柔组合桩及桩间土组成的复合地基,其承载力是由桩和桩间土共同提供的,通过刚柔组合桩的施工,实现对桩间土的挤密加固,充分发挥和利用地基土的承载潜力,有效地解决软土地基承载力不足的问题。提出刚柔组合桩复合地基及其复合模量的基本概念、承载力及复合模量的计算方法、检测方法;实践表明,刚柔组合桩复合地基具有较好的技术和经济效益。Based on the engineering practice and testing results by various inspection methods, the combining method with the deep mixing method around the rigid pile to compact and strengthen the soft soil is presented and discussed. The concept of rigid pile-deep mixing pile composite ground is put forward. The computation methods of bearing capacity, and the test method of rigid pile-deep mixing pile composite ground are presented. The engineering practice proves that the rigid pile-deep mixing pile composite ground has the advantages of good technical and economic effects.
