Life Loss Evaluation of Dam Failure Based on VOF Method
The life loss model of dam failure based on standard k-ε model coupled with the volume of fluid (VOF) method is studied in this paper. The improved Graham method is adopted to estimate the life loss of dam failure. The Gongming reservoir in Shenzhen city is taken as a case study. The calculated life loss is between 7970 to 10504 in the situation of no warning and very fuzzy public comprehension degree which is extremely serious; between 2031 to 3395 in the situation of no warning and very clear public comprehension degree; between 1335 to 2217 in the situation of full warning and very fuzzy public comprehension degree; and between 5 to 13 in the situation of full warning and very clear public comprehension degree. The results indicates that warning and public comprehension degree have a great impact on life loss. Research results can offer decision basis for accident warning and disaster prevention and reduction.
