船闸布置在弯道凹凸岸附近时通航条件分析

统计了枢纽中通航建筑物的布置现状,阐述了枢纽中船闸布置的有关规定,重点对通航建筑物布置在凹岸或凸岸附近时的边界、水流和航行条件作综合分析.分析表明:船闸布置在凹岸时的有利条件多于凸岸;当船闸引航道口门区处在弯道段时,会受斜向水流与弯道水流的共同作用,增加船舶(队)进出口门的难度;当连接段处在弯道段时,船舶(队)受到弯道水流与航线夹角和船队轴线与航线夹角的双重作用,船舶操舵较顺直河段困难.同时需研究船舶(队)回转半径与操舵角的关系.

Analysis of navigation condition of the lock located along the concave and convex banks of bend channel

The actuality of navigation structures layout is summarized in this paper;and some regulations of lock layout in the hinge are explained.The comprehensive analysis of boundary water flow and navigation condition is done.The results indicate: the advantage of being located along concave bank is more than that along convex bank;when the approach channel entrance area of the lock is located along the bend channel,joint action of oblique flow and bend channel flow will occur and the difficulty in ship(team) entering or going out of the entrance is increased;when connecting section is located along the bend channel,shipping rudder opermion is more difficult than straight channel when the ship(team) is under the actions of the bend channel flow,navigation line and the axis of ship team.Some relations,such as the relation between turning radius and rudder angle of ship(team),and the relation between stroke and relevant factors,should be studied.
