Abstract: In this paper the mechanism of toe-shooting method is studied through model experiments and numerical simulations.By utilizing tracing particles,the authors establish a whole physical diagram of replacing seaooze with rockfills,and then describe the mechanism of toe-shooting.The process of toe-shooting is simulated by using LS-DYNA dynamic FEM progam,and its feasibility is verified by comparison with experimental data.
