Smoothed particle hydrodynamics (SPH) is a meshfree particle method based on Lagrangian formulation, and has been widely applied to different areas in engineering and science. This paper presents an overview on the SPH method and its recent developments, including (1) the need for meshfree particle methods, and advantages of SPH, (2) approximation schemes of the conventional SPH method and numerical techniques for deriving SPH formulations for partial differential equations such as the Navier-Stokes (N-S) equations, (3) the role of the smoothing kernel functions and a general approach to construct smoothing kernel functions, (4) kernel and particle consistency for the SPH method, and approaches for restoring particle consistency, (5) several important numerical aspects, and (6) some recent applications of SPH. The paper ends with some concluding remarks.

It is desired to resolve soil contamination with reduced costs. "Insoluble treatment" is a soil improvement method for heavy metal containing soil, which uses soil mixers to mix soil and soil improvement liquid agents. To reduce the costs of this method, soil mixers have to be optimized. However, it is not achieved due to the lack of theoretical knowledge on mixing solid with liquid. Therefore, a numerical model to simulate the dynamic behavior of solid and liquid is on the development in this study using Smoothed Particle Hydrodynamics (SPH) method. To validate the numerical model, several experiments were carried out and numerically reproduced. The comparisons of the results showed that the numerical model replicated a liquid flow with an error rate of 2.1% and a seepage flow with an error rate up to 26.1%. Especially, the water distribution in the soil pores was highly improved with absolute gaps in volumetric water content up to 4.4% in the porosity range of 10% -90%. For the water absorption into dry sand, the simulation result became more realistic by concerning soil suction.

“…The other is split phase model, in which each phase of the mixture satisfies its own governing equation, and the interaction between mixture model will satisfies other equation, which is determined by model. Bui et al [3] proposed a spilt phase model, in which the soil is regarded as an elastic-perfectly plastic material and the water as a Newtonian fluid. The interaction between two water and soil was modeled by the Darcy's law and pore water pressure.…”

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.
