摘要
本文通过对四桩承台的载荷试验结果的分析,介绍了群桩在复合地基中的工怍性质,分析了整个加载过程中该复合地基试验的桩土应力比的变化,得到了桩土应力分布规律,指出了四桩承台下复合地基桩土应力比的极大值即为地基加固后的允许荷载值。
Based on the data obtained from field four-pile loading tests, the behavior of Cement-Stabilized Soil Pile foundation was discussed, and the variation of stress ratio of pile and soil during loading process was analysed. It was found that the ratio reached its maximum when the foundation reached its allowable load.
