白石水库泥沙淤积与减淤方法的研究

Research of Siltment in Baishi Reservoir and Siltment Reduction Method

白石水库泥沙淤积严重,牤牛河与大凌河交汇区的淤积尤其严重,将形成"拦门沙坎"把库区分成上下两部分,影响白石水库正常运行。文章分析认为水库初设时的异重流排沙和泄空排沙的减淤方法,受各种客观因素制约,无法实施,并对牤牛河交汇区挖槽减淤方案进行了试验研究,证明挖槽减淤对减缓库区淤积效果十分显著。

Baishi Reservoir is serious in silting , especially at the junction of Maoniu River and Daling River,which will divide the reservoir area into two parts up and down and affect the normal operation of the Baishi reservoir.By analyzing, this paper conforms that the silt reduction method is affected by various objective factors and can't be implemented smoothly,and the test research was conducted for the silt reduction scheme of dredging for deposition reduction at the junction area of Maoniu River,showing that dredging for deposition reduction is very useful.
