摘要
结合塔山电厂相关工程的现场试验,研究处理前后的湿陷性黄土地基,在不同深度沿桩体径向不同位置土的物理参数变化规律,同时结合载荷板试验,得出桩距为1.05 m时,单桩挤密影响范围为1.25D及处理后的复合地基承载力提高3倍多的结论。
Combined with site experience in Tashan Power Plant Engineering,the change rule of soil physical parameters along vertical length of pile in different depth of treated or untreated collapsible loess foundation is studied.Meanwhile combined with load plate test,it is summarized that influence range of single pile compaction is 1.25 D when pile distance is 1.05 m and that the bearing capacity of composite foundation increases over 3 times after treatment.
