现有大坝警情诊断方法在信息处理和结果表述上存在不足, 因此基于盲数理论, 对反映大坝性态变化的警情 因子所表征警情状况进行盲数描述, 然后采用AH P 法( 层次分析法) 进行因子指标权重确定, 继而对各因子警情状 况依据盲数运算法则进行计算分析, 将结果归一化处理后得到以盲数形式表征的大坝综合警情。利用汤河水库现 有监测资料进行实证研究, 结果表明利用该方法对大坝警情进行盲诊断, 效果良好。

In this paper , a blind diagnosis ana lysis method for the early war ning o f dam w as pro po sed based on the blind number theo2 r y. First, the w arning status reflected by w arning factor s was described in the blind number fo rm. Seco nd, the index w eig ht of each factor was determined by the AHP met ho d, and thus the war ning status o f each war ning factor can be calculated and ana2 lyzed using the blind number calculat ion algo rithm. Finally , the results o f each w arning factor w ere per formed no rmalizat ion pro2 cessing to o bta in the dam compr ehensive w arning in the blind number form. Based on the mo nitor ing data of Tanghe reserv oir, this met ho d can pr ov ide a blind diagnosis to the ea rly w arning o f reserv oir dam w ith g ood effect s.
