| Abstract: | 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. |
