Abstract: From the point of view of practical applications of seepage analysis for high dams with large reservoirs, this article builds a brand new measuring method, namely sonar flow velocity vectors measuring method, in which the latest sonar technology is used to detect the path of dam seepage. Also, the article introduces the conceptual model——the seepage energy measuring method, which detects seepage by measuring the flow energy changes. As well, some key technical problems in the double medium solid-liquid flow synchronous measurement for potential disease detection of dam leaking are solved by Bernoulli equation and mass-conservation equation. By integrating the achievements both in software and hardware which can be directly used in the picturing hydrogeological parameter, a complete set of 3D dynamic digitalized visual function system has been established. This 3D dynamic digitalized visual function system can be used widely, such as sonar probe data acquisition, sonar flow velocity vector measurement, computer function panel displaying, mathematical modeling of hydrogeological, the general calculation formula for the existence of ground water and confined water within void water, crack water and karst water, as well as numerical calculation imaging. Some innovative application achievements are provided for fast measurement of complex seepage flow field in deep water, precise positioning and multi-media display. At the same time, a seepage measurement case of a concrete face rockfill dam (CFRD) is presented, for reference.
