三门峡水库对黄河冲淤分析

为了分析多沙河流上水利工程对水沙运动规律的影响。根据三门峡工程的运用实践，实际资料以及以往的研究成果，应用系统工程方法分析了三门峡水库对黄河冲淤的主要原因，结果表明，水利工程对多沙河流水运动特性的影响具有一定的规律。

Analysis of Sanmenxia Reservoir Induced Scouring and Silting in the Trunk of the Yellow River

Sanmenxia water control project is the first multi purpose project built on the trunk of the Yellow River.The constructiou of Sanmenxia project has caused great changes in scouring and silting in the middle and lower course of the Yellow River. Through the practice of Sanmenxia project, valuable experiences have been accumulated concerning the understanding and harnessing of the Yellow River and the construction and management of projects on a muddy river. By use of the collected data and research results, and the method of system analysis, the main laws of scouring and silting caused by the reservoir are developed in this paper, which conform to the law and characteristics of water and sediment movement in muddy river.
