| 摘 要： | 原设计人工挖孔桩底端扩大直径，部分桩孔遇复杂地质条件无法扩底，经论证改为变截面人工挖孔桩，其扩大直径部位位于桩的中部（有坚实岩层的位置）。竣工后经检测承载力和沉降值均达到设计要求，桩基工程获得成功。

| Abstract: | In the orginal design, the diameters of man-dig piles were enlarged at their tips. Due to the complicate geological condition, it was impossible to do so. Therefore, the position of the enlargement was changed to the middle of a pile where a hard rock layer is located.After installation, both bearing capacity and settlement of piles met the design requirements. |
