摘　　要：结合实际工程,介绍了碎石桩与CFG桩组合处理软土地基的施工技术和质量要求,并将CFG桩、碎石桩的静载荷试验检测结果与理论计算结果相比较。分析结果表明,加固后的复合地基承载力和沉降量满足工程设计的要求。该方法对淤泥软土地基的处理具有实际价值和广阔的市场前景,可为类似工程参考。Combined with practical work, the construction technology and quality control of gravel pile ＆ CFG pile treating soft soil foundation are introduced. The results of the static load tests on gravel pile and CFG pile foundation are compared with those of the calculation. The analysis results show that both the bearing capacity and settlement of composite foundation meet the need of engineering design. The method of gravel pile ＆ CFG pile treating soft soil foundation has great practical value and bright market prospect, and it can be reference for similar engineering.
