摘　　要：对光滑粒子流体动力学(SPH)的发展背景、理论基础等进行了介绍,并分析了SPH方法在海冰和河冰模拟、具有自由表面的流动等方面的应用,作为一种无网格的纯Lagrange方法,在和其他方法对比的基础上列举了其主要优缺点,结合目前国内外研究成果总结了改善缺点的对策。The development background and theoretical basis of the Smoothed Particle Hydrodynamics （ SPH ） are introduced herein, and then its applications on the simulations in aspects of the sea ice, the river ice and the free-surface flows etc. are analyzed. As a meshless pure Lagrange method, its major advantages and disadvantages are listed on the basis of the comparison with the other methods and the countermeasures to improve its defects are summarized based on the recent domestic and overseas studies as well.
