| 摘 要： | 大坝风险后果综合评价涉及众多评价因子,各因子间存在大量不确定性,将线性加权和法应用于大坝风险后果的综合评价,以江西5座水库为例,应用层次分析法计算水库溃坝生命损失、经济损失、环境影响及社会影响等因子的权重,通过后果严重系数确定大坝风险等级并对其进行排序。结果表明,若发生溃坝事件,5座水库大坝后果均十分严重,属特别重大事故,评价结果客观合理。研究表明,线性加权和法能够较客观地反映大坝风险程度,具有概念清晰、过程直观、计算简单等特点,为大坝风险后果综合评价提供一条新途径。

| Abstract: | This paper aims at introducing a renovated hazard assessment model for the consequences caused by the dam failure based on the linear weighted method.Since such dam failure hazard assessment involves a lot of correlative factors characteristics of uncertainties,it is necessary to avoid subjective factors as much as possible.In this way,linear weighted method is expected to make the complex uncertainty factors visualized.The method requires a thorough analysis and evaluation of the objects,serious coefficien... |
