| Abstract: | Finite element numerical calculation is used to systematically study ground surface settlement, subjacent bed settlement, penetrating deformation for the upper and lower parts of pile, and lateral deformation of foundation soil etc, discuss the stresses variation laws of pile and geo-grid. The research results will serve as a guide in the design and construction of similar projects. |
