摘　　要：引入Stokes二阶水波理论,建立了对海洋工程中大尺度综合型圆柱式结构波浪载荷的二阶修正统一积分算式。通过对波势特征解法的推广及引入干扰波叠加法、最小二乘法,使原仅适合于轴对称单柱的二阶散射波浪载荷快速积分算法可完全适用于类型广泛的任意型实用圆柱的计算。几则实例(圆台,单、双柱)的计算检验了该方法的有效性。By introducing Stokes second order water wave theory,the unified integral formulae have been presented to predict the second order diffracted wave forces on large scale circular cylinders. With the use of the characteristic solution method, the interferential wave theory and the least square principle,the fast integral method used for single vertical circular cylinder has been proven to be also suitable for arbitrary kinds of circular cylinders. Several computing examples (including conical cylinder, single surface piercing cylinder and a pair of vertical cylinders)are given to make a verification of the presented theory.
