船舶模拟器在引江济汉通航工程与长江交汇口布置中的应用

对采用船舶操纵模拟器进行通航建筑物平面布置优化的方法进行了论证,建立了代表船舶的操纵运动数学模型,并根据国家规范对代表船舶的操纵性进行了率定。用船舶操纵模拟器对引江济汉通航工程与长江交汇口的平面设计方案进行了研究,结果表明设计方案下代表船舶在交汇口的最大通航上限流量仅为15 000 m3/s,不满足设计要求。优化方案加大了上下游连接段的弯曲半径,进而提高了上下游航线的转弯半径,减小了航线上的横流,使船舶有足够的空间调顺船位。

Applying of ship handling simulator in junction layout of the Yangtze River and water diversion project from the Yangtze River to Hanjiang River

The method of applying ship handling simulator to optimize the layout of navigation structures was analyzed and proved in this paper.The maneuvering mathematical model was built and verified by national standards.Using ship handling simulator,the layout design scheme for junction of the Yangtze River and water diversion project from the Yangtze River to Hanjiang River was studied.The results show that： the maximum navigable discharge in the design scheme is 15 000 m3/s,which cannot satisfy the requirements of design.The bending radius for connection section of upstream and downstream is enlarged in optimization plan.Then the route of upstream and downstream is enlarged and the cross flow is decreased.Ships have enough room to adjust the motion.
