大坝健康诊断是一个充满不确定性的复杂非线性问题,已有的健康诊断方法难以描述其中的不确定性.针对监测信息中存在的不确定性,在分析了监测信息不确定性内涵的基础上,将专门研究不确定性问题的信息熵理论引入到大坝健康诊断之中,利用熵的基本概念确定大坝安全综合评价中的指标权重(熵权),利用互信息概念识别和挖掘大坝监测信息中蕴含的异常状况,利用模糊熵概念研究大坝健康诊断中的复合不确定性问题,从而为大坝健康诊断提供一些新的研究思路.

Dam health diagnosis is a complicated nonlinear problem with a variety of uncertainty, and it is difficult to describe the uncertainty by the existing health diagnosis methods. Based on connotation analysis of the uncertainty in monitoring information, the information entropy, which is a specialized the-ory for uncertainty problems, is introduced to research dam health diagnosis. And some new ideas are provided, such as, the index weight (entropy weight) of dam safety comprehensive evaluation can be de-termined by the basic concept of entropy, the abnormal situation contained in the monitoring information can be recognized by the concept of mutual information, and the composite uncertainty problems in dam health diagnosis can be studied by the concept of fuzzy entropy.
