Abstract

As the important non-engineering measure of safety management of reservoir dam, risk analysis on dam-break flood is of great importance in improving the level of safety management of dam in our country. It studies techniques of risk analysis on dam-break flood, i.e., dam-break mode of arch dam and calculation of break flow discharge process, compilation of flood risk diagram, assessment of potential losses, etc., discusses applicable conditions of subsection model method and overall model method for analysis on dam-break flood from the aspects of the sharp of reservoir area, development process of break hole, terrain materials of reservoir area, etc. in detail, and carries out analysis and research on risks of dam-break flood of Shimen Reservoir of Shaanxi Province: conducting analysis on dam-break flood through overall model method, estimating the potential losses of life through D&M method, estimating direct economic losses through method of loss ratio and estimating indirect economic losses through coefficient method. The results show that risk analysis on dam-break flood is the important method for effectively decreasing or avoiding losses, and it shall select the most possible engineering condition with combination with facts of engineering to conduct risk analysis on dam-break flood.
