摘要
对沪杭高速公路粉喷桩试验段桩土表面压力和沉降实测结果作了分析与研究,同时进行了刚性基础下的荷载试验,并与柔性路堤的实测结果作了对比分析。结果表明,柔性路堤下粉喷桩复合地基为竖向桩体与地基组成的各向异向体,桩与土承受的荷载压力是不均匀的,其沉降是非协调的。
A field test study on composite foundation of DJM pile at Shanghai-Hangzhou expressway was described. A field loading test under rigid foundation had also been done, which was compared with the measurement under flexible load of embankment. According to the analysis, the composite foundation of the DJM pile under the flexible embankment should be anisotropy body composed with the pile and the subgrade soil. It was different with the pile top and the subgrade soil as well as settlement.
