摘　　要：对于岩溶地区基础形式和地基处理方法的研究具有重要的工程意义。结合工程实例介绍了岩溶地区普通桩基础向刚性桩复合地基的优化设计过程,并利用刚性桩应在基础范围内布置的特点提出了一种对褥垫层施加侧限的方法,且现场静载试验也验证了该方法的合理性。Research on form and handling method of foundation has crucial significance in civil engineering. Based on a project case, optimization design process of transforming pile foundation to rigid-piles composite foundation is introduced. Under the circumstances that rigid piles are required of arranged in boundary of foundation, a new method of side restrictions on cushion is discussed and be verified rational within the result of static load test.
