摘　　要：以相似理论为基础 ,设计并完成了一组较大型的室内碎石桩复合地基模型试验 ,获得了许多有益的试验数据。通过对试验资料的分析 ,得到了碎石桩复合地基孔隙水压力、桩土应力比的变化关系 ,并在此基础上 ,对碎石桩复合地基作用机理进行了深入探讨。On the basis of similarity theory, a set of large-scale laboratory model experiments of gravel pile compsite foundation is designed and accomplished, some useful experimental data are obtained, and from which, the relationship of pore water pressure with load and pile-soil stress ratio with time are gained. Moreover, the work mechanism of gravel pile composite foundation is studied.
