摘要
由于大坝安全性态综合评价是一个多层次、多指标的复杂分析评价问题,既要考虑单个测点、单个项目反映的大坝局部安全性态,更要考虑大坝多个测点、多个项目反映的大坝整体安全性态,为此提出了安全评价集的表示方法.通过对安全评价判据的分析,结合模糊集理论,研究了大坝安全评价判据的表示方法、结论表达,以及综合评价等不确定因素的处理方法,应用模糊集理论对大坝的安全状况作出评价,建立了大坝安全综合评价模型.应用实例表明,该模型是可行的.
Comprehensive evaluation of dam safety is a complex multi-hierarchy and multi-index evaluation problem. Not only the local safety behavior based on a single measurement point and a single item but the entirety safety behavior based on multiple measurement points and multiple items should be considered. Based on the safety evaluation criterion analysis and fuzzy set theory, the representation methods of dam safety criteria and treatment methods of uncertain factors are studied. The dam safety comprehensive evaluation model is established using the fuzzy measure and fuzzy integration theories. An application shows that it is practical and effective.
