船舶失控漂移模型在防波堤水域的应用研究

建立防波堤水域船舶失控漂移模型，设定防波堤工程所在海域的自然条件、防波堤口门有效宽度、进出港口船舶尺度等参数。通过设定船舶在防波堤口门外失控点至防波堤口门的距离，计算船舶在偏航、风、流共同作用下从失控点开始至防波堤口门的横向漂移量，根据计算结果来判断船舶是否有与防波堤发生碰撞的危险性。

The Application of Ship Out-of-control Drift Model in Breakwater Area

A out-of-control drift model for a ship in breakwater area was established, in which the parameters of natural conditions in breakwater area were setting, as well as the effective width of breakwater entrance, ship＇s size and the distance between the out-of-control site and the transversal drift distance. The paper discussed the drift state of the out- of-control ship under the influence of yawing, wind and current. The possibility of collision between ship and breakwater on basis of the calculated results was analyzed.
