针对大坝安全综合评价中多指标权重的确定问题,在引入非参数统计中的Spearman秩相关系数与不同赋权方法有机集成在一起以确定多指标组合权重,避免了单一数学模型自身缺陷易造成权重失真现象的发生,工程实例验证了此方法有效可行。
In order to determine the weight of multi-indicator in comprehensive assessment of dam safety, Spearman’s rank correlation coefficient and non-parametric statistics are integrated organically with different weighting methods to determine the weight of multi-indicator combination and avoid the defect of single mathematical model The occurrence of weight distortion phenomenon, engineering examples verify that this method is effective and feasible.
