Abstract

The underwater landslide often appears in the construction of underwater facilities, causing serious personal property damage. It is of great significance for engineering design and disaster prevention to simulate the large deformation and two-phase flow problems. Smoothed Particle Hydrodynamics (SPH) method is a Lagrange meshless method, with inherent advantage for simulating the large deformation and two-phase flow problem. In the SPH method, appropriate boundary treatment method can guarantee higher accuracy. Boundary particle massless scheme is proposed, and underwater landslide is simulated by SPH method and split phase model. The law of motion and the dynamic response of underwater landslide are studied. The influence of physical parameters such as hydraulic conductivity and dilatancy angle on the process of underwater landslide is analyzed. The accuracy of massless boundary particle method is proved.
