摘要
惠州东江水利枢纽工程闸坝砂砾卵石地基采用振冲碎石桩加固处理,取得了较好的经济效益。对振冲碎石桩复合地基承载力采用载荷试验检测,得出复合地基承载力特征值,并计算出变形模量,为工程设计提供了可靠依据。试验表明:振冲碎石桩复合地基的承载力特征值为300 k Pa,满足设计要求。就复合地基静载荷试验检测结果进行分析,为同类工程试验检测分析提供了参考。
The sluice dam foundation composed with sand and gravel of the East River Hydro-Junction Project in Huizhou is treated by vibro replacement stone column and obvious economic effect is achieved. The characteristic value of beating capacity and deformation modulus of the composite foundation are obtained by static load test to provide a basis for engi- neering design. The static load test shows that the characteristic value of bearing capacity of the composite foundation is 300kPa meeting design requirements. In the paper, the static load test results are analyzed for similar project reference.
