LI Da-ming1, LIU Jiang-chuan1,2, XU Ya-nan1(1.Key Labortoty of Harbor & Ocean Engineering, Ministry of Education, School of Civil Engineering, Tianjin University, Tianjin 300072, China; 2.Changchun Institute of Technology,Changchun 130012, China)  
The paper studies the smooth particle hydrodynamics (SPH) method and establishes model of discharge through crest orifice on dam. The author applies the SPH model to the flow of liquid with free surface on Laxiwa dam, simulates the process of the discharge of the surface outlet. The water recharge boundary is used in the model. The paper gives the an analysis of the numerical pressure and the experimental pressure. The results indicate that it is possible to simulate and research high-speed flow using the smooth particle hydrodynamics method.
