摘　　要：收集了邯郸市6个代表性工程36组深层搅拌桩复合地基静载荷试验数据,借助无量纲计算模式,计算出不同荷载组合下深层搅拌桩复合地基承载力可靠度指标,并分析了不同荷载效应比ρ对可靠度指标的影响,为评价规范法设计的复合地基的可靠性提供了一种客观方法。The 35 test data of deep-mixing pile composite foundations from six projects are collected. The reliability index of the deepmixing pile composite foundations is calculated by the non-dimensional calculation mode, and the influence of the reliability index with the alteration of load effect specific p is analyzed. The objective method witch valuing the reliability of the composite foundation is put forward.
