武广客运专线路基段采用CFG桩,路基与桥梁过渡段采用路基灌注桩,桥梁段采用桥梁灌注桩。采用桩端反射波曲线特征分析法判定桩身混凝土施工质量;采用单桩静载试验,其CFG桩单桩承载力大于600 kN、路基灌注桩和桥梁灌注桩单桩承载力均大于2 000 kN,满足设计要求。
The embankment section of Wuhan-Guangzhou Passenger Dedicated Line uses CFG piles, and the subgrade and bridge transition sections adopt subgrade filling piles, and the bridge sections adopt bridge pours. The pile-end reflection curve characteristic analysis method is used to determine the quality of pile-concrete construction. The single-pile static load test shows that the bearing capacity of CFG pile is greater than 600 kN, and the bearing capacity of pile foundation is more than 2 000 kN ,Meet the design requirements.
