内河挖入式港池水流特性及泥沙淤积研究进展

Research progress on flow characteristics and sediment deposition in inland river dredged harbor basin

挖入式港池具有充分利用港口岸线资源、不影响主航道、较好的泊稳条件,且不妨碍航道泄洪等优点,在航道狭窄地区有广泛的应用前景。但其往往容易引起港内泥沙淤积,而港内的泥沙淤积与其水流运动特点息息相关。文章从内河挖入式港池水流特性、泥沙淤积、主要研究方法和减淤措施等方面梳理相关研究成果,系统地展示了内河挖入式港池水流运动和泥沙淤积的机理特性、研究热点和发展趋势,为挖入式港池的防淤减淤和开发应用提供了参考依据。

The dredged harbor basin is a common layout form in large inland river ports,which is formed by manual excavation and dredging.This kind of layout has the advantages of making full use of the port shoreline resources,not affecting the main channel,good berthing stability conditions,and not hindering the channel flood discharge.It has a wide application prospect in the narrow channel area.However,the inland river dredged harbor basin is easy to cause sediment deposition in the harbor,and the sedimentation in the harbor is closely related to the characteristics of water movement.This paper reviewed the relevant research results from the aspects of the flow characteristics,sediment deposition,main research methods and sediment reduction measures of the inland river dredged harbor basin,systematically demonstrated the mechanism characteristics,research hotspots and development trends of the flow movement and sediment deposition.It provides an important reference for sediment reduction,development and application of the inland river dredged harbor basin.
