船舶操纵仿真的狭长通航隧洞航行安全研究

Ship Handling Simulation in Research on Safety of Navigation in Narrow and Long Tunnel

通航隧洞作为一类新型的过船设施,具有通航宽度窄、水深浅、能见度不良和环境封闭等特点,船舶在隧洞内航行时船舶操纵难度大、船员心理压力高,船舶在通航隧洞内航行驾驶研究方面在我国还几乎处于空白。以拟建的乌江思林二线通航隧洞工程作为对象,采用航海模拟器构建隧洞通航环境模型、代表船型模型,通过开展隧洞操纵仿真试验、制动冲程操纵试验和小舵角操纵试验等3种试验,分析船舶在通航隧洞内不同阶段的航行特点与风险,提出适用于狭长隧洞通航船舶的航行方案,为隧洞内航行安全保障措施的制定提供有力支撑。

The Navigation tunnels are a new type of navigational passage with the features of narrow channel,shallow water,dim light and isolated environment.To safely navigate through a tunnel is a challenging task and the navigators will experience high pressure.Few research on tunnel navigation has been conducted.Research on Navigating the tunnel in Siling Route Number 2 of Wujiang River under planning is conducted.The navigational handling procedure,stopping maneuvering process and small ruder angle maneuverability of typical ships are simulated with a marine simulator.The scheme for navigating through the tunnel is proposed.
