大坝监测资料分析中环境量对效应量影响综合评价的加权面积法

用距离的概念来描述大坝监测资料分析中环境量对效应量的整体影响效应. 首先讨论了多种距离定量化准则, 其中加权面积距离是以分量过程线围成的面积对其基准值的矩经量纲归一处理后得到的值; 然后论证了使用加权面积定义距离的合理性并给出了确定距离基准值的方法, 为确定各个分量占效应量的比例提供了定量的依据. 最后给出了应用实例, 证明了该法的有效性.

Weighted area algorithm for comprehensive assessing the influence of environmental variables on affected variables in analysis of dam safety monitoring data

The concept of distance is introduced to describe the comprehensive influence of environmental variables on affected variables in dam safety monitoring data analysis. Definitions of distance for various variables are defined. The weighted area distance is defined as the moment of the area, formed by the variation graph of environmental component and the base line, about the base line, Then, the rationality of the weighted area distance is demonstrated and the approach to calculate the base value is deduced. An application example is given for demonstration and the validity of proposed method is verified.
