基于船模的枢纽通航及码头靠离泊试验研究

Experimental research on hub navigation and wharf berthing and unberthing based on ship model

传统的通航条件影响研究,不能全面准确反映航道水流条件和边界条件对船舶航行的综合影响以及船舶与航道水流条件的相互作用。利用小比尺船模测控技术,对大渡河沫水航电枢纽上、下游航道通航水流及上游码头靠离泊进行试验研究。结合试验研究成果进行定量与定性分析,提出枢纽上下游航道最高通航流量为4 500 m3s,为枢纽工程方案的设计优化及上游码头靠离泊方案的选取提供了科学可靠的数据基础。

The traditional research on the influence of navigation conditions cannot fully and accurately reflect the comprehensive influence of waterway flow conditions and boundary conditions on ship navigation and the interaction between ship and waterway flow conditions.Using the small scale ship model measurement and control technology,the experimental study is carried out on the navigable water flow in the upper and lower waterways of Dadu River Moshui navigation-power junction and the upstream wharves berthing and unberthing.This paper carries on the quantitative and qualitative analysis combined with experimental study results,proposes hub upstream and downstream channel maximum navigable discharge of 4 500 m 3 s,which provides a scientific and reliable data basis for key project plan design optimization and unberthing upstream port scheme selection.
