长江下游裕溪口水道上段开通公用航道可行性研究

从裕溪口水道上段的航道自然条件出发,通过对不同年份河床演变分析、航道尺度核查及水位统计分析,提出水道开放公用航道的可行性及开通方案,为水道后续开通工程提供技术支持。结果表明:按照现有的自然条件,裕溪口水道上段具备开通一定等级航道的条件。但该水道开通涉及芜湖长江大桥桥区通航环境改变,其开通可行性还需通过对大桥通航安全进行专题研究后确定。若开放为公用航道,可考虑将裕溪口水道上段航道维护尺度与下段保持一致。

Feasibility research on opening of public waterway on Yuxikou channel upper segment in lower Yangtze River

Based on the natural condition of Yuxikou channel upper segment, this article proposes the feasibility of opening public waterway and scheme of the channel by analyzing the riverbed evolvement and verification of waterway scale to provide technical supports for subsequent opening project. The results show that the Yuxikou channel upper segment has the condition of opening a public waterway. However, the opening of channel will result in a change of navigation environment in Wuhu Yangtze River bridge area, so the feasibility shall be verified by the monographic research on the navigational safety. The maintenance dimension of Yuxikou channel upper segment can be decided referring to the lower segment when opening.
