[摘要]  通过振动沉管碎石桩复合地基平板载荷试验、现场堆载试验，监测沉降变形和孔隙水压力的变化规律，对复合地基的加固效果进行了分析。经过碎石桩处理后的复合地基沉降量有效减小，孔隙水压力加速消散，土体的有效应力不断增加，地基变形以垂直向的压缩固结变形为主，达到了复合地基的处理效果。

Abstract: On the basis of the gade settlement and pore water pressure detected in the plate loading test and static load test in situ, the reinforcement effect of composite ground with crushed rock file is analyzed. After being treated with crushed-rock piles, the settlement of compound ground reduced effectively, the dissipation of pore water pressure accelerated, and the effective stress of the soil body increased continuously. the deformation of the ground is vertical mainly and the soil is consolidated.
Keywords: crushed rock pile; settlement; pore water pressure; detection
