| 摘 要： | 某地基处理原拟采用CFG复合地基。但由于地层情况复杂 ,施工难度大 ,决定采用CFG桩和人工挖孔桩进行地基处理 ,但是这种处理方案可能会引发地基不均匀沉降从而对上部结构产生不良影响 ,因此合理的的选取人工挖孔桩桩间距非常重要。通过对四种桩间距情形下地基的三维沉降分析 ,选取了合理的人工挖孔桩桩间距 ,解决了这一工程难题.

| Abstract: | A CFG composite foundation was planed, but it is very difficult to be treated in construction due to complicated geologic stratum. Thus, two pile diameters(φ400 and φ800) are adopted to improve the foundation. But theplaned foundation could undergo different settlement of foundation and brings bad influence on building because of different pile diameter. So it is very important to select the appropriate pile spacing. To solve this problem, this paper compares four different pile spacings by 3D settlement analysis of composite foundation, then an optimum plan is put forward. |
