长江下游江阴水道下段开通上行副航道可行性研究

Feasibility research on opening up subchannel in lower section of Jiangyin waterway in the lower Yangtze River

结合江阴水道的航道自然条件,分析江阴水道的河床演变、航道条件及经济效益等,研究江阴水道下段开通上行副航道可行性,并提出相应的开通方案。结果表明,按照现有的自然条件并考虑利用一定的水位,江阴水道下段具备开通一定等级上行副航道的条件。考虑到江阴水道航道条件虽然近年来良好,但航道关系情况复杂,建议开通副航道等级为I-4,按照通航3000吨级海船及7000吨级内河船要求确定航道尺度,航标配布采用虚拟航标。

Combining with the natural condition of Jiangyin channel,we analyze riverbed evolvement,channel conditions and economic benefits of Jiangyin waterway,research the feasibility of opening up subchannel in lower section of Jiangyin waterway,and propose the corresponding opening scheme.The results show that the lower section of Jiangyin waterway has the conditions of opening up a certain grade subchannel according to the existing natural condition and using a certain water level.Although the conditions of Jiangyin waterway are good in recent years,the channel relationship is complex.It is suggested to open subchannel of grade Ⅰ-4,the channel dimension is determined according to the requirements of navigable 3,000-tons sea vessel and 7,000-tons inland vessel,and the virtual navigation mark is used to navigation mark.
