Dam Break Risk Analysis of Small Reservoirs Based on FTA

HU Jinmin

Abstract

Dam break reasons and failure chains of small reservoirs are summarized with taking Shatian Reservoir for an example.FTA analysis model of dam break is built.Dam break probability of reservoir is calculated under different temporal scenes.Then risk factors for influence of dam break and main strategies of preventing dam break are analyzed.The results show that Shatian Reservoir does not appear dam break events in future 40 years.Strengthening risk management has positive meanings to control reservoirs impounding level and prevent dam break risk.
