浅水航行船舶下沉量的确定

A Determination of squat in Shallow Water

此文通过对浅水域中航行船舶吃水增加而产生下沉现象分析，包括船舶在临界、亚临界、超临界速度段相应阻力、纵倾以及下沉的讨论，给出船舶在浅水域航行时确定船舶下沉量的几种方法。

：Recent evidence has shown that squat has been happened when a ship moving in shallow water.This paper explains some reasons for ship squatting in shallow water and illustrates the corresponding resistance, trim and sinkage at both sub_ critical, critical and super_critical speeds. Mean while, the paper also gives several methods to predict the squat in shallow water and alerts crew to avoid resultant accidents.
