摘　　要：针对港口工程防风单点浮筒系泊力计算问题,根据《港口工程荷载规范》和Daidola公式,求得船舶在风、浪、流荷载下的平衡位置;在此基础上叠加瞬时的波浪冲击力,建立单点系泊系统的受力模型。考虑到系泊船在风、浪、流共同作用下会产生偏荡运动,参考军标《防风系船水鼓》中的相关公式,对比物理模型试验结果,提出风、浪、流各力的组合修正系数,提供了一种可供工程应用的系泊力计算思路。该方法可供类似工程初步确定防风浮筒参数,为后续物理模型试验提供必要的基础。Regarding at the calculation of mooring force of windproof single point mooring system in harbour engineering,the equilibrium position of the ship under wind,wave and current loads is obtained according to Load Code for Harbour Engineering and Daidola formula.On this basis,the instantaneous wave impact force is superimposed,and the force model of the mooring system is established.Considering that the mooring ship will produce sway motion under the combined action of wind,wave and current,referring to the relevant formula form in the military standard Anti-typhoon mooring buoy system,and comparing the results of physical model test,the combined correction coefficient of wind,wave and current forces is proposed,which provides a solution for engineering application.The method in this paper can be used for the engineering under similar conditions to preliminarily determine the parameters of windproof buoy,and provide a necessary basis for subsequent physical model tests.
