摘　　要：由于海洋平台砰击过程中可能出现波浪破碎等现象,波浪砰击载荷预报是海洋平台数值模拟的难点。本文基于直角网格方法,建立了适用于模拟海洋平台波浪砰击过程的三维数值模型。在介绍模型数值方法基础上,首先对模型造波与消波精度进行了验证;其次,对某半潜式平台进行模拟,以验证模型模拟波浪砰击过程的准确性;最后,利用该模型对某四柱海洋平台波浪砰击过程进行了研究。结果表明,当前模型可以较好地模拟海洋平台波浪砰击过程中的波浪破碎、爬升和砰击等现象。Due to the complexity of wave breaking during the slamming process,the prediction of wave slamming load is a major difficulty in the numerical simulation of offshore platform.Based on the Cartesian grid method,a three-dimensional numerical model for simulating the wave slamming process of offshore platforms was established in this paper.On the basis of the numerical method of the model,the accuracy of the model on wave generation and wave damping was verified.Then a semi-submersible platform was simulated to verify the accuracy of the model to simulate the wave slamming process.Finally,the model was used to investigate the wave slamming process of a four-column offshore platform.The results show that the present model is able to simulate wave breaking,run-up and slamming greatly in the process of wave slamming.
