红山水库的淤积上延问题是非常严重的。本文根据二十年来的实测资料,进行了初步的整理分析。提出了主要影响因素是三角洲顶部段的河床形态及冲淤特性、河床糙率和侵蚀基面。得出三角州顶部段的冲淤规律,在此基础上予估了今后淤积上延的发展。最后提出了利用水草拦截进库泥沙,在一定范围内调动淤积体向上游发展,以延长水库寿命,然后给予控制的建议。
The problem of siltation upset of Hongshan Reservoir is very serious. Based on the measured data over the past two decades, this article conducted a preliminary analysis. The main influencing factors are the riverbed morphology, scouring and silting characteristics, river bed roughness and erosion basement in the top section of the delta. Obtained scouring and silting law of the top section of the delta state, on the basis of which to estimate the development of deposition in the future. Finally, the suggestion was put forward that using aquatic plants to intercept the sediment into the reservoir and mobilize the sediment to the upstream in a certain range in order to prolong the reservoir life and then give control.
