摘　　要：对低潮位时纵向船台下水的危险情形——艉跌落和艏跌落进行分析,提出设置浮箱的新工艺解决方案。并通过实例计算验证,得出了浮箱的最佳设置位置和体积的规律,给出了浮箱体积的建议公式。This article analyzes the dangerous situation of longitudinal ship launching from the slipway during low tide condition, namely, stern dropping off and bow falling; and proposes a new process to solve the problem by setting buoyant boxes. The proposed formula for determining the optimal position and volume of the buoyant boxes are obtained through calculation and validation based on examples.

关 键 词：纵向船台下水 浮箱 艉跌落 艏跌落
