文章通过对影响船舶吃水的主要因素,如船舶对波浪的响应、横倾引起的吃水变化、浅水中船舶的下坐以及航道底部等的分布规律的研究,拟合出其概率密度函数,然后使用蒙特卡洛(Monte Carlo)仿真船舶搁浅概率,其中船舶对波浪的响应采用了先进的粘性流数值计算方法。该模型可为受限水域航道建设和船舶安全通航提供参考。

In this paper, a deterministic model of ship under keel clearance is presented, which contains a set of random variables caused by ship maneuvering, including the vertical motion induced by wave, the heel during ship turning, the squat in sallow water and hydrographic data of seabed. They are represented by cer-tain distributions, and the ship basic response to typical wave is predicted by a CFD method. Via Monte Car-lo simulation, the stochastic uncertainty of a ship under keel clearance is observed, and the grounding prob-ability can support channel construction and vessel traffic safety analysis in restricted waterways.
