Abstract:
In the numerical analysis of laterally loaded pile-soil interaction, the classical Lagrangian model under the large soil deformation or rough pile-soil interface will cause convergence problems due to soil plastic damage and great mesh distortion, which leads to a large discrepancy between the calculation results and the actual situation. In this paper, a numerical model based on the coupled Eulerian-Lagrangian (CEL) method was proposed to investigate the laterally loaded pile-soil interaction and the variation of ultimate soil resistance (USR) acting on the pile side. The results show that the USR calculated by the CEL model was consistent with the theoretical values and the Lagrangian model results in the literature, which indicates that it is appropriate to study the laterally loaded pile-soil interaction behavior using the CEL model. In pile-soil interaction problems involving large deformations, the CEL model describes well the soil flow behavior around the pile and has signific
ant advantages in the application.
