黄河流域中小型水库淤积物清淤相变与管道输沙研究进展
Research progress on phase transformation during sediment dredging and pipeline sediment transport in small and medium-sized reservoirs of the Yellow River Basin
摘要
Abstract
There are about 3100 small and medium-sized reservoirs in the Yellow River Basin,62％of which are located on the Loess Plateau,where sedimentation is relatively serious.Sedimentation has become a restrictive factor affecting the normal functioning of small and medium-sized reservoirs in the basin.The composition of fluvial deposit has a complex and diverse feature,including sand,flexible materials such as branches and water plants and organic matter.To reduce siltation,dredging is often conducted by manual methods,which generally includes two key steps of fluidization phase change and pipeline transportation.Scholars have conducted a lot of studies on the mechanism of sedimentation phase change and pipeline transportation energy consumption of these small and medium-sized reservoirs.However,we lack of research on reducing sedimentation by highly-efficient and environment-friendly ways under the new situation.Makes an introduction on domestic and international research progress in sediment composition,fluidization-phase transformation mechanisms,pipeline sediment transport dynamics of small and medium-sized reservoirs in the Yellow River Basin and dredging efficiency optimization technologies.The study identifies critical future research priorities including prototype sediment characteristics and siltation mechanisms in reservoir systems,fluidization phase transformation mechanisms of sediments under the forces of jet-flow and reamer,compatibility relationships between the forces of jet-flow and reamer and the suction slurry flow rate in the pipeline,energy consumption mechanisms in diverse sediment pipeline transport and intelligent dredging technology of high efficiency,which may provide scientific and technological support for sediment regulation of small and medium-sized reservoirs in the basin under the new situation and requirements.关键词
