摘　　要：为了保证平潭海峡公铁大桥修建后船舶能够安全航行,依据原航道的分布与建好桥梁之后的变化特点,利用建模方式设计建桥后船舶在该水域航行的路线,再用船舶模拟器进行仿真航行试验,最后获得建桥之后船舶的安全航线。驾驶人员在仿真当地的风、流等条件下用模拟器操纵设计的航线,并在模拟航行中查找设计的问题。仿真模拟操纵船舶在进入鑫海码头、鼓屿门航道和大小练岛航道时,修正了航线中的转弯半径,并用航标标注新航线。桥梁新建之后水流和水深都会发生变化,船舶直接试航存在危险,用模拟器验证建模方式所设计的航线可以极大地减轻危险性并提高生产效率。In order to ensure that the ships can safely sail by and off the berthing after the construction of the Pingtan Strait Road and Railway Bridge,the distribution of all the channels before the construction of the bridge is analyzed,and then the navigation route of the ships in the water area after the construction of the bridge is designed by modeling method.In order to confirm the rationality of the new design route,the ship simulator is used to conduct simulated navigation test in the channel,and the problems of simulated navigation are found from the test.During the simulation voyage,the water area of the ship is designed to fully conform to the local wind and flow conditions.The pilot uses the simulation maneuver to find out whether there is any problem in the course design,and then modifiable the course for easy navigation according to the problem.When the ship entered the simulation operation of Xinhai Wharf,Guyu Gate Channel and Daxiaoliandao Channel,it was found that the turning radius of the original designed route was too small.After the test of modifying the turning radius for many times,the new route was determined by moving part of the beacon,and the channel in line with the corresponding waters was finally designed.After the dredging of the waterway or the construction of a new bridge,the water flow and water depth will change,so it is easy to cause accidents if the ship is directly used to explore the waterway.For example,the basic route can be obtained by designing the route with modeling and conducting the trial voyage with the simulator.Finally,the risk can be greatly reduced and the production efficiency can be improved by using the ship for the route.
