摘　　要：刚性—亚刚性桩复合地基(CM复合地基)作为一种较新颖的地基形式,相较于单一刚(柔)性桩复合地基,在能大幅提升地基承载力同时,还可以更灵活地控制地基变形,目前国内鲜少此类地基形式的检测案例。论文结合工程实例分析,针对CM复合地基采用多桩型复合地基平板载荷试验,根据试验工序总结出五大检测要点。试验前设计验算了褥垫层厚度、承压板面积、截面尺寸和钢筋配置,试验中对4个基准桩位移进行监测,试验结果验证了装置的可靠性。本研究为多桩型复合地基平板载荷试验检测全过程提供参考作用。As a relatively novel form of foundation,compared with a single rigid(flexible)pile composite foundation,the rigid and sub-rigid pile composite foundation(CM composite foundation)can greatly improve the bearing capacity of the foundation and control the deformation of the foundation more flexibly.Combined with the analysis of engineering examples,this paper adopts the multi-pile composite foundation slab load test for CM composite foundation,and summarizes five key detection points according to the test process.Before the test,the thickness of the cushion layer,the area of the bearing plate,the cross-sectional size and the configuration of the reinforcement were calculated,and the displacement of the four reference piles was monitored in the test,and the test results verified the reliability of the device.This paper provides a reference for further exploring and improving the quality acceptance inspection method of multi-pile composite foundation.
