• Abstract: Whether the groundwater from the dam foundation or dam abutment to the downstream or the downstream slope, or toward the adjacent river valley leakage, is adverse to the project, the need to adopt engineering measures to deal with. Although examples of impermeable or weakly permeable interlayers having a decisive effect on dam foundation seepage are easy to understand, this is often overlooked by many people, who simply rely on the WPT value to decide whether to install impermeable curtains. The use of favourable hydrogeological factors can result in a significant reduction in the scope of the survey and the workload of the base treatment. 地下水无论是从坝基或坝肩流向下游或下游边坡，或朝向临近河谷渗漏， 对工程来说都是不利的，都需要采用工程措施进行处理。尽管像不透水或弱透 水夹层对坝基渗漏有决定性的影响的例子是那么容易理解，但这又常常被不少 人忽视，而只是根据 WPT 值去决定要否设置防渗帷幕。利用有利的水文地质因 素，可使调查范围和基础处理工作量大大减少。
