摘要 三门峡水库于1960年9月建成并投入运用已38年。本文分析了渭河下游在近期(1992年以来)的淤积发展情况,潼关高程一直居高不下,渭河下游泥沙淤积急剧增加,主槽过洪能力锐减,同流量洪水位迅速抬升,洪水灾害日趋频繁,防洪形势十分严峻,本文并对泥沙淤积发展的原因进行了分析研究。 It has been 38 years since the Sanmenxia Reservoir was built. The paper analyzes the sedimentation processes of the lower Weihe River, one of the major tributaries at the head of the reservoir, since 1992. The sediment deposition in the river increased rapidly; The capacity of flood conveying in the main channel of the river decreased dramatically which resulted in the rapid raising of flood stage. Therefore flood disasters occurred frequently and the situation of flood prevention became very sustere. The paper slso analyzes the reasons of the deposition processes, so it can provide scientific experience for the reservoir construction on the rivers with high sediment load.
