摘　　要：当前港口航道与海岸工程相关专业在实验中时间和场地受限,实验教学效果较差。该文将基于拉格朗日法的SPH技术用于波浪特性虚拟仿真实验,通过求解SPH形式的N-S方程,借助以质点为单位并基于GPU加速进行后期渲染得到的水槽实验结果和港口实验结果可以真切直观地展现波浪运动特性。该方法可为学生提供更加生动、立体的学习环境,激发学生的兴趣和创新性,在巩固学生对以波浪运动特性为核心的港航专业知识的理解、拓展基础理论、培养工程实践能力方面都具有积极的推动作用。At present, the experimental teaching effect of port, waterway and coastal engineering is poor due to the limited time and space. In this paper, the SPH based on the Lagrange method is applied to the virtual simulation experiment of wave characteristics. By solving the N-S equation in the SPH form, the flume experimental results and port experimental results obtained by GPU accelerated post-rendering with particles as the unit can truly and intuitively show the wave motion characteristics. This method can provide students with a more vivid and 3 D learning environment, stimulate their interest and innovation, and play a positive role in consolidating students’ understanding of port and shipping professional knowledge with wave motion characteristics as the core, expanding basic theory and cultivating engineering practice ability.
