通过对水泥土搅拌桩进行单桩静载荷试验和复合地基静载荷试验，对水泥土单桩承载力在工程中的实际表现以及与复合地基承载力的关系的研究，结果表明：水泥土单桩的实际承载力一般难以达到设计或理论计算的要求，在复合地基承载力的计算中应做适当折减。并对目前复合地基承载力的计算公式进行了修正 Through the static load test of single pile and the static load test of composite foundation for cement-soil mixing piles, the actual performance of cement-soil single-pile bearing capacity in engineering and the relationship with the bearing capacity of composite foundation are studied. The results show that: cement-soil single pile The actual bearing capacity is generally difficult to meet the requirements of design or theoretical calculations, and appropriate reductions should be made in the calculation of bearing capacity of composite foundations. The correction formula for the bearing capacity of composite foundations has been revised
