摘要
采用振冲碎石桩方法对大面积回填土进行地基处理,通过载荷试验和动力触探方法对振冲法处理后的地基土进行检测检验,地基处理效果良好,复合地基地基承载力特征值不小于200kPa,满足设计要求。
Using vibro-replacement stone piles method to the large area of back fall foundation treatment, through the load test and dynamic sounding method of vibro-flotation treatment foundation soil test, foundation treatment effect is good, composite foundation bearing capacity characteristic value of not less than 200kPa, meet the design requirements.
