太赫兹技术在大坝渗流实时监测中的应用探索

o monitor seepage of earth-rock dam is an important and effective method for its safety. This paper summarizes the current state of technologies of dam seepage (health) monitoring and points out their advantages and problems respectively. A new technology based on terahertz spectrum is proposed for dam seepage monitoring and the development and application effect of this technology both in the domestic and foreign are introduced. The imaging of concrete seepage detection in real-time monitoring is given as well. It is then discussed that promotion application of terahertz technology has much value and good prospect in dam seepage monitoring field.
