摘　　要：苏南丘陵区某市大部分小型水库建于20世纪，坝型一般采用均质土坝，水库大坝多为人工挑筑而成，填筑质量较差，坝体透水性达弱-中等透水，长时间运行渗透水流的作用使坝身防渗能力不断弱化，防渗处理一直是小水库消险工程的主要工作内容。本文针对小型水库特点，介绍三种适合小型水库坝身防渗的方法，分别分析了其特点并应用于典型工程实例中，总结了防渗设计要点及三种方法适用性，为类似小型水库的坝身防渗消险设计提供参考依据。Most small reservoirs of a city in the hilly area of southern Jiangsu province were built in the 20th century. Dam type is generally homogeneous earth dam, These reservoir dams were mostly artificial construction with poor filling quality and the dam water permeability is in weak to medium grade. For long time operation, the anti-seepage effect of the dam has been weakened, so anti-seepage treatment has always been the main work of risk elimination project for small reservoirs. According to the characteristics of small reservoirs, we describe 3 anti-seepage treatments suitable for the dams of small reservoirs, and their characteristics are analyzed and applied to typical engineering examples. We also summarize essential points of anti-seepage design and the applicability of the three methods, which can provide reference for the anti-seepage design of small reservoir dam.
