摘要

水库大坝的溃决将会对下游自然、经济和社会产生灾难性影响

对溃坝洪水灾害的脆弱性分析有助于科学制定减轻灾害损失措施。提出了一种基于数据包络分析模型定量计算溃坝洪水灾害脆弱性的方法

并结合实例加以应用。应用结果表明

该方法具有可行性

并得出实例研究区中的小河区和南明区属于溃坝洪水灾害的高脆弱区

花溪区属于中脆弱区和云岩区属于低脆弱区

可为该区制定减灾措施提供一定参考价值。

Abstract

Dam break can cause disastrous consequences to natural

economic

and social systems in the downstream area. A nalysis of vulner ability to dam-break disaster helps develop measures of mitigating disaster losses. This paper presents a quantitative method for evaluating vulnerability of dam-break disaster based on data envelopment analysis method with the downstream area of Huaxi dam as an example. Results show that Xiaohe District and Nanming District have high vulnerability

Huaxi District has middle vulnerability

and Yunyan District has low vulnerability in the study area. The study also provides some reference values for developing measures of mitigating disaster losses.
