| 摘 要： | 为提升超大型船舶在长江口深水航道内的双向通航能力,以实际航道尺度为边界条件,在三自由度MMG模型的基础上,考虑浅水效应、船间效应和岸壁效应,建立船舶操纵运动模型。利用MATLAB对10万吨级的散货船和集装箱船交会进行仿真,并对风、流和两船不同间距对船舶交会的影响进行研究。仿真结果表明,长江口深水航道的宽度可基本满足船宽之和在90 m内的超大型船舶交会。

| Abstract: | In order to enhance the two way passing ability of very large ships on the deepwater channel of the Yangtze River estuary, based on the MMG model with 3 degrees of freedom, a ship manoeuvring motion model is built, where the boundary condition is the actual scale of the deepwater channel, and the shallow water effect, the ship to ship interaction effect and the bank effect are considered. The encountering of the 100 000 t bulk carriers and the 100 000 t container ships is simulated with MATLAB, and the effects of the wind, the current, and the different distance between the ships on the encountering of the two ships are analyzed. The simulation results show that the deepwater channel width of the Yangtze River estuary can basically satisfy the encountering demand of two very large ships, where the sum of their widths is no more than 90 m. |
