摘　　要：混凝土防渗墙属于重要的地下隐蔽工程,准确进行检测非常重要。介绍了钻孔电视成像技术的检测原理与检测方法,并结合工程实例,利用该方法检测防渗墙内部各种类型的质量缺陷和墙底沉渣厚度,缺陷部位准确、状态清晰,与传统的钻孔取样法相比,具有明显的优越性。Concrete cut-off wall is an important underground concealed work. It＇s important to make an accurate test. The test principle and methods of borehole TV imaging technology have been introduced, and the method has been used to test the various types of defects and the thiekness of the bottom sediment inside the cut-off wall in project examples. The test results show that the defects positions are accurate and status is clear. Compared with the traditional drilling and sampling method, it has the obvious superiority.
