摘要
依据实测资料,应用灰色理论,通过各影响量与效应量的灰色关联分析方法可确定大坝各环境因素对效应量的量化影响程度,并以工程实例验证了该方法的有效性。结果表明,该法简单实用,能有效确定水压分量、温度分量和时效分量在大坝效应量中所占的比例,为评价大坝的运行状态提供依据。
In order to analyze the influence degree of the influencing factors to the changes in dam safety behavior,it is necessary to quantitatively analyze the influence degree of the factors, such as water level, temperature and aging effects to the effect-variable of the dam. Based on field data, this paper established the grey theory to obtain the quantitative influence degree of the influencing factors to the effect-variable, and to extract the component proportion of hydraulic components, temperature components and aging effects components in the dam effect-variable through the grey correlation analysis of the influence quantity and the effect-variable, besides, the effectiveness of the method has been verified. The results show that the method is simple and practical, it can quantitatively analyze the influence degree of the water level, temperature and other environmental-variable to the dam effect-variable, and could provide evidence for analyzing and evaluating the properties of the large dam during its operation.
