中文摘要：

沿倾斜河岸航行作为船舶在限制水域中航行的一种特殊情况，水底以及岸壁的存在对航行船舶的安全性会产生重要影响。若操纵不当，常会使船与水底、岸壁距离太近而发生触底、碰撞事故。该文以KCS（CB=0．651）船模为例，采用基于RANS方程求解的CFD方法，计算其以恒定速度平行于倾斜河岸航行时受到的横向力和转首力矩，分析了河岸倾角、船-岸距离、水深对船舶所受水动力的影响。计算中基于低速假设忽略了自由面兴波的影响。

英文摘要：

For a ship sailing along a sloping bank, as a special case of ships sailing in restricted waters, the water bottom and bank will have significant influences on the ship navigation safety. In this case, if operated improperly, the ship may be too close to the bottom and bank, and collision accident may happen. In this paper, taking the KCS （CB = 0.651） ship model as an example, CFD method based on solving RANS equations is applied to calculate the lateral force and yaw moment on the ship sailing along a sloping bank with constant speed. The influences of the sloping angle, distance from ship to bank and water depth on the hydrodynamic forces are analyzed, while the effect of free surface elevation is neglected under the assumption of low ship speed.
