Inverse Analysis of Dam Seepage Field and Seepage Safety Assessment Based on Monitoring Data of Osmometer

Aiming at the seepage problem of earth-rock dam, this paper uses the real in-situ monitoring data collected by the osmometer buried in the earth-rock dam, and uses the method of combining numerical simulation with on-site monitoring to inverse the seepage parameters of materials in each partition of the dam. According to the calculated distribution of dam seepage field under different reservoir water level operation conditions, the dam seepage safety status is evaluated based on the conventional dam seepage failure type discrimination criteria. The research results of this paper can provide reference for the design and safe operation of earth-rock dams.
