坝基帷幕体的防渗性能及其时效可由传感器采集到的地下水宏观动态反映出来,而在异类多个传感器数据融合的过程中,常常出现各个评价指标不一致的现象。为消除这种现象,采用Bayes融合方法,首先验证各个传感器的可靠程度,确立正确的关系矩阵,然后将各传感器的可靠程度模糊化,进而给出各传感器的综合支持程度指标,最后给出融合结果。将其应用于某坝13坝段帷幕体防渗效果分析,结果较为符合规律。经分析知,2003-2008年间帷幕体防渗效果呈现了阶段性衰减,其中2005年和2008年为该坝段帷幕体防渗性能的相对明显衰减时期。建议加强监测,为必要时采取工程措施提供依据。
The seepage control performance and its aging of dam foundation curtain body can be reflected dynamically by the macroscopic dynamic of groundwater collected by sensors. In the process of heterogeneous data fusion of multiple sensors, the phenomenon of inconsistency of each evaluation index often appears. In order to eliminate this phenomenon, using Bayes fusion method, the reliability of each sensor is verified, the correct relationship matrix is established, then the reliability of each sensor is obscured, and then the comprehensive support index of each sensor is given. Finally, result. Applying it to dam curtain dam seepage control effect analysis of 13 dam, the result is more in line with the law. According to the analysis, the anti-seepage effect of curtain body during 2003-2008 shows a period of decay, of which, 2005 and 2008 are the relative decay periods of anti-seepage performance of curtain body. It is suggested to strengthen monitoring and provide basis for taking engineering measures when necessary.
