摘　　要：根据汝州市滕口水库坝基渗漏特性的不同有针对性地实施堵漏施工,坝体坝基结合部采取多孔联合灌注、速凝封闭待凝方法;坝基断层裂隙带采取聚丙烯酰胺-惰性材料与水泥-聚丙烯酰胺复合浆液灌注方法;坝前渗漏点与深部绕坝渗漏带采取速凝砂浆灌注、间歇待凝方法,堵漏工程的实施有效解决了该水库存在的岩溶渗漏问题。According to the seepage characteristics of dam foundation of Tengkou reservoir in Ruzhou,the construction of plugging has been carried out. Multihole combined infusion and quick-setting sealing for solidation methods are used on the connecting part of dam foundation,whereas composite grout method of pouring polyacrylamide and inert material,cement and polyacrylamide is used on the fault fissure zone of dam foundation. Pouring quick-setting mortar and wait for hardening method is used on the face of dam leakage point and deep leakage around the dam. The implementation of the project solves the problem of karst leakage in the reservoir effectively.
