| 摘 要： | 对于某五层住宅楼软弱地基采用粉喷桩处理后，铺设一定厚度的砂垫层形成粉喷桩复合地基，之后随机分别抽取三根单桩和桩的复合地基进行静载荷试验，分析单桩和复合地基的受力特性与沉降之间的关系，并在载荷板下的桩中心、桩边缘内外两侧及桩土中各放置压力盒，根据作用在桩－土的应力测试结果，分析整个加荷过程中该类复合地基的桩土应力比的变化规律。

| Abstract: | The paper introduces that the soft ground foundations w ere consolidated by DJM pile for a five-story building and , then, the single pi le and the pile composite ground foundation were tested with field test. The ult imate bearing capacity and displacement of the single pile and the composite gro und foundation were analyzed. On the other hand, the stress ratio of the composi te ground foundation pile-soil was also measured and analyzed. |
