根据溃坝洪水演进特征及其对经济财产的破坏作用,提出了一种基于淹没范围区划的溃坝经济损失评估方法。为便于确定溃坝洪水财产损失率,将溃坝洪水淹没范围划分为6种区域溃决区、毁灭区、重灾区、中灾区、轻灾区及安全区,制定了溃坝洪水淹没区划标准及每种分区财产损失率的建议表。为避免溃坝洪水淹没范围区划中的不相容问题,提出了基于物元模型的溃坝洪水淹没范围区划方法。该评估方法简便快捷,可以节省工作量,实现快速评估。
Abstract
A new method of estimating the economic loss caused by dam-break by dividing flood inundated area is proposed based on the characteristics of flood propagation and property damage. In order to determinate the property damage rate, the flood inundated area is divided into six zones breach zone, destructed zone, severely affected zone, medium disaster zone, slightly affected zone and safe zone. The criteria of zoning and the property damage rate of each zone are given. Furthermore, a method of dividing the inundated area is proposed based on matter-element model to avoid inconsistency. The estimation method saves workload, and is convenient and rapid.
