窝水库大坝自1972年运行后即陆续发现裂缝，渗漏日趋严重，敌对其进行水泥灌浆处理．通过压水试验可知，灌浆效果不理想，分析其原因包括以下几方面：（1）施工工艺；（2）水泥材料自身特性；（3）运行环境．通过分析，笔者认为，水泥灌浆技术在发展的同时，尚有一些问题，主要是：水泥属颗粒状材料，对于较细裂缝难以克服拱效应，在可靠性方面有一定的局限性；由于材料本身的干缩特性及各种成分的不均一性，在抗溶蚀方面，影响其耐久性．放在应用中需进行具体分析．
After the dam reservoir was operated in 1972, cracks were found one by one and seepage was becoming more and more serious. Enemies were treated with cement grouting. Through the water pressure test shows that the grouting effect is not ideal, analysis of its causes include the following aspects: (1) construction technology; (2) cement material properties; (3) operating environment. Through the analysis, I believe that cement grouting technology in the development at the same time, there are still some problems, mainly: cement is a granular material, for smaller cracks difficult to overcome the arch effect, there are certain limitations in reliability; due to the material itself Shrinkage characteristics and heterogeneity of various components, in the anti-erosion, affecting its durability. On the application need to be analyzed.
