| Abstract: | Stress of the geogrid material,stress transmission characteristic of the geogrid material and the stress ratio of pile and soil of joined strength embankment of plain concrete pile and geogrid are analyzed and studied by the finite element analysis procedure ANSYS.And some valuable conclusions are obtained that the influence of the distance between the piles and the modulus of elasticity of the piles and soil among the piles on the stress ratio of soil and piles,and the geogrid′s drag stress′s dispersing characteristic.Then the basis is provided for fundamental research and the project application of this kind of composition foundation |
