| Abstract: | Taking into account the contact surface effect of pile with the soil in soft ground, a three dimension nonlinear FEA model was established for analyzing the interaction between pile and soil. A simulation was carried out on theperformance of load transition between pile and soil in certain typical soft soil region. Then the law of influence of some factors on the negative friction is analyzed, such as characteristics of pile and soil, parameters of contact surface of between pile and soil, soil structure and piling load. The results can serve as reference to the design and construction of pile under similar conditions. |
