| Abstract: | With a proposed displacement model, this paper takes into consideration the interaction of soil and piles and derives an analytical function of compressive deformation of stabilized layer of composite foundation under embankment. The frictional resistance between pile and soil and the pile soil stress ratio expressions are also obtained. A simple method is developed for computing the compressive deformation of the stabilized layer. |
