In the present research, numerical study of the effect of geometrical parameters of the spudcan on the bearing capacity and the rupture phenomenon of the spudcan punch in the soil, with a two-layer system of sand on clay, has been carried out using the Lagrangian-Eulerian couple method. In this research, ABAQUSE software was used for modeling the scenarios of the present research are based on the study of other past researches and considering the shortcomings of these researches. In this research, the geometrical parameters of the spud, including the influence of the spud's diameter, the angle of the spud's tip, and the thickness of the largest cross section of the spud are considered. The obtained results were compared with the results of other previous researches in order to evaluate the ability of the Lagrangian-Eulerian couple method in estimating the bearing capacity and the spudcan punch rupture phenomenon. The results of the research show that the desired geometric parameters, including the thickness of the sand layer, have a direct relationship with the load-bearing strength of the spudcan foundation. Also, the results show that different roughness parameters between clay and foundation and the thickness of the largest cross-sectional area of the spudcan have no effect on the bearing capacity and the rupture phenomenon in the soil. Also, the results obtained from the present research show that the experimental models of Lee et al 2013 and Hu et al 2014 have estimated the results less than the CEL model.
