坝基渗漏在大坝上下游水位差作用下，库水通过坝基岩土中的孔隙、裂隙或溶洞等通道向下游渗漏的现象。沿大坝两侧岸坡岩土中的渗漏称为绕坝渗漏。当坝基渗漏或绕坝渗漏的水量很大时,不仅会造成库水的流失,而且对坝基产生渗透压力,或对岩土中的微细颗粒产生冲刷,或对岩土中的可溶部分产生化学溶解等不良作用。为此，修建大坝时要对坝基渗流进行控制，将其不利影响减少到规定的安全范围内。根据岩土透水性质的不同，坝基渗漏可分为三种主要类型。①孔隙性渗漏:通过砂砾石孔隙产生的渗漏,一般呈均匀流，渗漏量的大小主要取决于土的粒度成分及其渗透系数。②裂隙性渗漏：通过岩石中节理裂隙产生的渗漏。当裂隙很多且互相切割时,渗流近似均匀流;当裂隙发育不均一或不规则时，渗流常呈脉状流。③管道式渗漏：通过石灰岩、白云岩等可溶岩中的溶洞产生的渗漏，渗漏量的大小取决于溶洞的大小和多少。这三种类型在坝基中可以在不同部位同时存在，也可以单独出现，主要取决于坝基的岩土分布和地质结构条件。控制坝基渗漏的方法很多。为减少坝基渗漏量，可以采用上游水平铺盖、垂直混凝土防渗墙、帷幕灌浆及堵塞溶洞等措施；为减小扬压力或渗流梯度，通常采用排水孔、排水廊道、减压井等工程措施。根据坝基地质条件和渗漏量情况选取上述方法中的一种或几种，上堵下排，就会获得良好的防渗效果。
