Concrete dam health state has been taken seriously in the field of structural health monitoring. A limitation in the current research is a lack of clear physical significance and reasonable interval division for better reflecting the development trend of the health state. This article introduces a comprehensive evaluation method that provides information on the fusion of different monitoring types and influences of degree weight. The analysis method of variation tendency for concrete dam soundness is proposed based on gray theory. According to the principle of analytic hierarchy process, this article introduces an optimization division method of evaluation grade interval for concrete dam health state. Based on this, a method based on multiple monitoring quantities is established through studies of determination methods for monitoring various quantities of weight, which aimed at evaluating concrete dam health state and solving the problem of comprehensive evaluation for concrete dam health in an effective manner. An existing concrete dam is presented and discussed to serve as the validation of the established theory.

结合灰色层次分析法的混凝土大坝健康状态综合评价方法

在结构健康监测领域,混凝土大坝的健康状况已得到重视。当前研究的局限性在于缺乏清晰的物理意义和合理的区间划分,无法更好地反映健康状况的发展趋势。本文介绍了一种综合评估方法,该方法提供了有关不同监视类型的融合以及度数权重影响的信息。提出了基于灰色理论的混凝土大坝合理性变化趋势分析方法。根据层次分析法的原理,介绍了混凝土大坝健康状态评价等级区间的优化划分方法。基于此,通过研究监测各种重量的确定方法,建立了基于多监测量的方法,旨在评价混凝土大坝的健康状态,有效解决混凝土大坝健康的综合评价问题。提出并讨论了现有的混凝土坝,以验证所建立的理论。
