摘　　要：大坝截渗墙属于地下隐蔽工程,由于施工工艺及质量控制等原因,其质量检测受多种因素制约。弹性波CT技术作为混凝土结构检测的常规方法,其理论基础与反演理论也日趋成熟。本文通过某水电站截渗墙质量检测的工程实例,采用跨孔弹性波CT技术方法,查找截渗墙墙体接头缝或混凝土不密实区,探讨弹性波CT技术在大坝截渗墙质量检测中的应用。The dam cutoff wall is one of the underground hidden projects.Due to the construction technique and quality control,the quality detection is restricted by a variety of factors.As is known,elastic wave CT technology is regarded as a conventional method of concrete structure detection and its theoretical basis and inversion theory are gradually becoming mature.In this paper,taking the cutoff wall quality detection of one hydropower station project as an example,it adopts the cross-hole elastic wave CT method to find the seam of the cutoff wall or not densifying area of the concrete.Then it analyses the application of the elastic wave CT technology to the dam cutoff wall quality detection.
