Abstract

Dam break is a serious social disaster, which causes a great deal of damage to the society and environment. In this paper, a 3D turbulence model coupled with the Volume of Fluid (VOF) method for the dam-break flood propagating is established, the loss of life resulting from dam failure is calculated by the modified Graham method, a statistical method is used for the economic loss, the main factors for social and environmental impacts are introduced, and finally the linear weighting method is carried out for comprehensive evaluation and analysis of dam-break consequences. The dam-break consequences of Dongwushi reservoir in Handan is taken as a case, the life loss, the economic loss, as well as social and environmental impacts are analyzed, and then a comprehensive evaluation of the dam-break consequences carried out.
