摘　　要：从Morison方程出发,对其进行适当变形、推演,最终得到一种可直接计算近海平台支撑物所受最大水平波浪力的计算方法。通过实例计算,得出不同情况下最大水平波浪力。将该计算结果与经典计算法所得结果进行对比,在实际情况下,该算法与经典算法所得结果相近。在工程项目初始阶段,可使用该方法进行综合估算。In this paper, an analytical solution for the direct calculation of the maximum wave force an a support of an offshore platform is realized through formula derivation and theoretical analysis of Morison ~quation. With the analytical solution,the paper calculates the maximum wave force of application examples, and be compared with the results of the traditional method. The numerical examples show that the results which are calculated with the method proposed in this paper can be estimated as equal to the results which ~re calculated with the traditional method. The solution allows the estimate of useful synthesis to be arrived at in the preliminary phase of the project.
