Abstract: Not all of seepage flow is reservoir leakage, so finding out the cause for leakage is important to take effective measures of seepage control. In this paper, a method of relation analysis to investigate and ascertain cause for leakage in embankment dams is put forward, according to this method the cause of leakage can be determined by calculating relation coefficient of seepage discharge to reservoir level or rainfall. Case study shows that this method of relation analysis proposed by this paper is simple and reliable.?

摘要： 并非所有的土石坝渗水都是水库渗漏，因此查明渗水原因对于采取有救的渗流控制措施是十分必要的。本文提出了土石坝渗水原因分析的相关分析法，即通过计算渗流强度与水库水位、渗流强度与降雨量之间的相关系数来判断土石坝渗水原固。实例研究表明，土石坝渗水原因相关分析法简单、可靠。
