根据某电厂粘性土地基的特点,通过对CFG桩低应变测试、桩体试块抗压强度、单桩复合地基载荷及柱间土承载力检测等试验分析,就承载力理论计算与实际测试结果间差异进行了探讨。提出了CFG桩原体试验方案。得出了CFG桩复合地基竖向承载力及设计参数。利用复合地基桩上应力变化关系,验证了复合地基桩处理方案的可行性。
According to the characteristics of clay foundation in a power plant, through the low stress test of CFG pile, the compressive strength of pile test block, the load of single pile composite foundation and the test of soil bearing capacity between columns, the theoretical calculation and actual test results of bearing capacity The differences are discussed. Proposed CFG pile prototype test program. The vertical bearing capacity and design parameters of CFG pile composite foundation are obtained. Using the relationship between the stress changes of the composite foundation pile, the feasibility of the composite foundation pile treatment scheme is verified.
