虾峙门口外30万吨级人工航道试通航观测研究

Observation studies during trial navigation of Xiazhimen 300 000 DWT artificial channel

以国内第一条建成、水深最大、通航条件非常复杂的30万吨级人工航道——虾峙门口外人工航道为研究对象,在航道试通航期间,国内首次采用30万吨级实船开展航道适航检验观测研究,并同步进行航槽开挖初期的阶段性回淤观测研究,以13艘30万吨级船舶实时通航参数及10个月监测水深数据为基础,进行了超规范航道设计参数合理性的验证,同时对航道建成后的适应性、稳定性、可维护性及安全性进行了多角度分析。经观测研究分析表明,虾峙门人工航道设计参数合理,满足设计船型安全通航要求,航道稳定性及可维护性较好。该研究成果为该航道安全通行、后期维护及通航规则制定提供了重要技术依据。

Xiazhimen 300 000 DWT artificial channel is the 300 000 DWT ehannel built for the first time with the maximum water depth and very complex navigation conditions in China. During the trial navigation of the waterway, 300 000 DWT large real ships are first used to carry out the observation studies of channel＇s adaptability in China, and stage siltation observation studies are carried out simultaneously in the early stages of channel excavation. By the basic data of 13 300 000 DWT ship＇s real-time navigation parameters and the depth monitoring data within 10 months, the rationality of the channel＇s design parameters which beyond the standard is verified, and the adaptability, stability, maintainability and security of the channel is analyzed comprehensively. The analysis shows that the design parameters of the channel are reasonable, the channel can meet the requirements of the design ship＇s safety navigation, and the stability and maintainability of the channel are better. These studies provide an important technical basis for the waterway traffic security, maintenance and navigation rule-making.
