摘　　要：冲孔灌注桩受施工工艺影响,即便持力层是坚硬岩土层,其受力仍表现为摩擦桩的性状,当受荷接近其极限承载力时,其工作状态为塑性支承状态。以厦门某工程为例,介绍了基于塑性支承桩概念的冲孔灌注桩复合桩基的设计方法,提出了设计建议,供工程设计人员参考。Punched cast--in--situ pile affected by the construction process, even if the bearing stratum is a layer of hard rock, still showed its charac- teristics of friction piles. When the load bearing capacity is close to its limits, its Working status is the plastic bearing state. An Example of a project in Xiamen is given to describe the design method of composite punched cast--in--situ pile foundation based on the concept of plastic bearing pile, and also some design proposals are made for reference.
