摘　　要：在恶劣的航海条件下 ,船舶的碰撞、搁浅、触礁等恶性事故的发生都将导致船舶的破舱进水 .船舶破舱进水后进水量的大小及所需的时间是驾驶员一直关注的问题 .为此建立了船舶破舱瞬时进水速度的计算模型 ,通过编程对船舶不同的破口大小及其位置进行实船计算 ,求出了船舶下沉、纵倾达到新的平衡水线甚至沉没所需的时间 .为驾驶员迅速判断船舶的破舱安全性 。Ship's collision, grounding or striking would result in flooding owing to hold damaged, while quantity and time of flooding are concerned by ship. In the paper, calculating model of instant flooding velocity is constructed. The time that vessel with different size and position of damaged openning reaches to new equilibrium even capsizing in sinking and trimming is obtained by program, which provides theory basis for captain to quickly appraise safety of damaged ship and make decision of rescue.
