长江口南槽航道疏浚工程实施效果与展望

Implementation effect and prospect of south passage waterway dredging engineering in the Yangtze estuary

长江口南槽航道疏浚工程2013—2015年现场实测资料表明,工程实施后南槽5.5 m航道实现了疏浚贯通,航槽稳定运行且易于维护,达到了预期的建设目标,并为南槽航道进一步开发创造了条件。同时,提出南槽航道后续开发建设应着重遵循的原则。研究成果可为长江口航道体系建设、上海市滩涂围垦和长江口综合整治等提供技术参考。

Based on the field measured data of year 2013 to 2015 implementation of the south passagewaterway dredging engineering in the Yangtze estuary, we know that the 5.5 m navigation channel is through thesouth passage after the dredging engineering construction, and the navigation channel is stable for operation and easyto maintenance, which achieves the desired construction target and creates conditions for further channeldevelopment of the south passage. Meanwhile, main principles to be followed in the further navigation channeldevelopment and construction of the south passage is put forward. The research results can provide technicalreference for the Yangtze estuary waterway system construction, Shanghai tideland reclamation and the Yangtzeestuary comprehensive regulation.
