摘　　要：混凝土防渗墙具有非常良好的防渗性能,目前在国内外水利水电工程中得到广泛的应用。但是,人们担心由于某些原因可能导致防渗墙出现裂缝或开叉。这些不利因素是否影响坝基的渗控效果和大坝的安全?本文就这些问题进行初步探讨,提出裂缝渗分析方法,并结合小浪底水利枢纽工程实例进行了计算和分析。Concrete cutoff has a very good property in seepage prevention, and is widely used in conservancy and hydroelectric power projects at home and abroad. But people are afraid that the imperious wall may crack for certain reasons,and that whether these infrior factors will affect the seepage control and the dam safety or not. The crack-seepage analysis theory is brought out. Practical calculations and analysis are conducted in connection with the Xiaolangdi water control project.
