| Abstract: | Combined with testing in site ,the changing law of collapsible loess foundation physical parameter before and after treatment at different depths,and along the pile of earth at different position＇s radial were studied. At the same time,combinied with loaded plate tests,the conclusions are obtained that the affected area compaction pile will be 1.25 D when the space is 1.05 m. and the bearing capacity of composite foundation improved more than 3 times of it before treatment. |
