Study on settlement calculation of deformable piles composite ground under flexible foundation

Research shows that flexible pile composite foundation has effective length.Firstly,according to the distribution form of skin friction on pile,the formula for calculation effective length is derived by shear displacement method under the assumption that pile and soil satisfy deformation compatibility condition.Secondly,compressed layer of composite foundation is divided into three layers for calculation.Amount of compression in reinforced area is calculated based on elastic theory,and calculati...
