摘　　要：利用CFG短桩复合地基、单桩、桩间土的载荷试验成果 ,得到了CFG短桩复合地基承载力计算公式中桩间土承载力折减系数 β值 。The β value of reducing coefficient for soil bearing capacity in CFG short pile combined foundation bearing capacity calculation formula was got through the load test on CFG short pile combined foundation, on single pile and on the soil between piles. It can be used as instruction to the future design of CFG short pile combined foundation.
