| Abstract: | Combined with indoor model experiment and theoretical research result, considering elastic plasticity of soil and highly nonlinear behavior between pile and soil, this paper establishes relatively reasonable numerical model of multi-element composite foundation. Through changing design parameters （such as pile diameter, pile length, pile modulus, cushion thickness and cushion modulus）, it carries out systematic research on the bearing capacity of multi-layer multi-element composite foundation, which is favorable to promote the development of engineering design and theoretical research for multi-element composite foundation. |
