中文摘要：
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AHP 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。
英文摘要：
The current dam warning diagnosis methods have the disadvantages in the information processing and result presentation. In this paper, a blind diagnosis analysis method for the early warning of dam was proposed based on the blind number theory. First, the warning status reflected by warning factors was described in the blind number form. Second, the index weight of each factor was determined by the AHP method, and thus the warning status of each warning factor can be calculated and analyzed using the blind number calculation algorithm. Finally, the results of each warning factor were performed normalization processing to obtain the dam comprehensive warning in the blind number form. Based on the monitoring data of Tanghe reservoir, this method can provide a blind diagnosis to the early warning of reservoir dam with good effects. Key words： blind number theory; dam; early warning diagnosis; Tanghe reservoir
