| Abstract: | Combining with practical highway engineering, this paper, by on-site monitoring of soil pressure in test section, analyzes the law that how pile-soil stress ratio changes with embankment filling height and time, concludes that the ratio change is resulted from compatible pile-soil deformation and load transfer; generalizes the main factors affecting this ratio; and proposes the range of this ratio. |
