船闸口门区布置及其通航安全判别标准

Layout of gate area of ship lock and criterion of navigation safety

针对应用《船闸总体设计规范》进行船闸引航道口门区及制动段布置时遇到的问题,从船舶通航安全角度阐述了船闸引航道制动段、口门、口门区和连接段的内涵。介绍了国内外现有船闸口门区通航安全判别标准并指出其存在的问题,分析引航道口门区的水流特性及船舶舵效原理,提出一种切实可行的船闸通航安全制动段水流条件判别方法,对船闸整体模型试验及船闸总体布置具有一定借鉴意义。

In view of the problems encountered in the layout of gate area and brake section in the approach channel of lock by applying the general design code of lock,the connotation of brake section,entrance,entrance area and connection section of the approach channel of lock are expounded from the perspective of shipping safety.This paper introduces the existing standards of navigation safety at home and abroad and points out the existing problems,analyzes the water flow characteristics in the entrance area of the approach channel and the principle of ship rudder efficiency,and puts forward a feasible method of judging water flow conditions in the brake section for lock navigation safety,which has certain reference significance for the whole model test and the overall layout of the lock.
