| 摘 要： | 胜利油田孤河水库系平原水库,其围坝由粉质砂壤土水力冲填而成,坝高仅5m,但运行中出现严重渗漏,为分析产生渗漏的原因,利用原位监测、同位素测量和渗流数值反馈分析方法进行了研究,研究证实,坝基存在贝壳夹砂的强透水层,是下游产生渗透破坏的主要原因,另外坝的建基面由于未清基,也是一条渗漏通道,为此建议采用垂直铺塑截渗,并在坝下游设置贴坡排水以保证渗透变形安全。

| Abstract: | The polder embankment of Guhe plain reservoir consists of silty sand loam,its maximum height being 5m.Serious leakages occur during operation.Prototype observation,isotop dilution method and seepage feedback analysis are used to analyze the leakage causes.It is found that the leakage results from the shell sand layer of embankment foundation and the poor foundation stripping.As a result,some seepage control and drainage measures are taken to improve the leakage of reservoir. |
