| Abstract: | Based on the formula, the paper simulates the process of spudcan slide in the soil, and now to construct a nu-merical method to analye the anti-slide force of spudcan. First of all, the paper researches the theoretical anti-slide formula from different paper, based on which, the finite element model of spudcan-soil system is built to, using CEL method and es-tablishing the required conditions, study on the flow deformation of soil and calculate the numerical result. Finally, the theor-etical result and numerical result are compared and discussed to compensate for the lack of theoretical formula and provide a accurate method to calculate the anti-slide force of spudcan. |
