摘要
文中拟采用灰色关联度法和属性数学方法对泥石流危险性进行评价,在确定参评因子后,依据泥石流单指标属性测度理论和多指标属性测度理论,建立单指标属性测度模型,在多指标属性测度模型中使用灰色关联度法计算影响因子权重,然后计算出评价对象的属性测度值,并通过置信度准则,完成属性识别分析,最后将该模型应用到工程实例中,以期能够给出更加客观的评价结果,对于泥石流防治设计提供科学性指导。
This paper intends to evaluate the risk of mudslides using the grey relational analysis method and attribute mathematical method.After determining the evaluation factors,a single-index attribute measurement model is established based on the single-index attribute measurement theory and multi-index attribute measurement theory of mudslides.In the multi-index attribute measurement model,the grey relational analysis method is used to calculate the weight of influencing factors,and then the attribute measurement value of the evaluation object is calculated.Through the confidence criterion,attribute recognition analysis is completed.Finally,the model is applied to engineering cases,in order to provide more objective evaluation results and provide scientific guidance for mudslide prevention and control design.
