摘　　要：分析影响船舶富余水深的因素,指出狭水道浅水域航行富余水深确定的核心是船舶下沉量的确定,利用浅水船舶流体力学的有关理论,探讨狭水道浅水域船舶航行下沉量计算.比较了各国不同水域确定船舶富余水深的几种方法,得出相对比例法确定富余水深的方法较为科学,既考虑了理论分析的要求,也考虑了实际经验所提出的要求.The paper analyzes the factors which affect ship＇s UKC （Under Keel Clearance）, and points out that the kernel of calculating the UKC in the shallow water of narrow channel is to make certain the squat of ship. By means of the relevant theories of the fluid mechanics of vessel in shallow water, the paper discusses the calculation of the squat of ship in the shallow water of narrow channel. Comparing several methods of calculating the UKC in different water areas, it is concluded that the relative proportion method is comparatively scientific in that it meets not only the requirements of theory analyses, but also the requirements of practical experience.
