50 年来泥沙研究所主要研究进展

50年来,泥沙研究所几代科技人员勤奋工作,兢兢业业,对我国工程泥沙问题进行了大量针对性的研究,为一些重大工程提供了技术支撑。在三门峡、小浪底和三峡水库上下游的泥沙问题解决,黄河和长江等河道演变研究和治理、黄河口演变和治理等,无不包含着我所职工的心血。不少科研人员,在所里组织和个人自觉开展相结合的形式下,不间断地开展泥沙运动基本理论研究,经过一批研究人员的艰辛努力,研究成果颇为丰硕,如浑水异重流、泥沙运动随机理论、非均匀悬移质不平衡输沙、高含沙水流、水库淤积及河床演变等理论成果,其中一些达到了国际先进甚至领先水平,为将我院提升为国际一流科研机构做出了重要贡献。

Main research development by the Department of Sediment Research in the past 50 years

For the past 50 years, scientists and engineers in the Department of Sediment Research, IWHR have conducted and fulf illed massive research projects on sedimentation and gained fruitful achievements, which have provided strong technical supports to the construction of many key hydro-projects in China. The outstanding contributions by the Department manifest in various aspects, such as, solution of sediment problems in the upstream areas and downstream channels of Sanmenxia Reservoir, Three-Gorges Reservoir, Xiaolangdi Reservoir, as well as the fluvial process and regulation of the Yangtze River and the Yellow River Estuary, etc. Plentiful research results have been achieved in the fundamental studies of sediment transport, such as, density current of muddy flow, stochastic theory of sediment transport , nonequilibrium transport of non-uniform sediment, hyper-concentrated flow, reservoir sedimentation and fluvial process, etc. It is shown that some of the results have reached the advanced level even leading position in sedimentation science at home and abroad.
