| 摘 要： | 为大渡河瀑布沟水电站截流工程选择截流方案进行水工模型试验。试验采用宽戗堤截流,设计戗堤顶宽分别为25 m和60 m的两种试验方案。试验结果表明:龙口水面线第二次跌落时,方案1在戗堤下游坡脚线附近形成的舌状体大于方案2,更能充分利用突扩造成的局部水头损失。因此选择方案1作为最终截流方案。其合理性得到了工程实践的验证,具有一定推广价值。

| Abstract: | A hydraulic model test was conducted in order to select a reasonable scheme for the river closure project of Pubugou Hydropower Station.We adopted a broad-crested banquette in the model test with two schemes of its crest widths of 25 m and 60 m respectively.The test results show that the tongue-like current formed near dam-toe line in the downstream of the banquette in scheme 1 is larger than that in scheme 2 when water surface level at closure gap drops for the second time;therefore,scheme 1 is selected,in... |
