矿区建筑物采动损害等级评定的灰色关联模型

Grey correlation model for assessment of mining damage grade of buildings in mining area

基于灰色理论关联模型,选取引起建筑物损坏的水平变形、曲率变形、倾斜变形等3个地表变形因子,建立建筑物灰色关联评价模型,结合各因子权重确定评价单元对于评价标准的关联度,按照关联最大原则确定建筑物的损害等级。与传统评价方法相比,该方法是利用引起建筑物损害的内在因子进行评价,而传统评价为静态建筑物情况,评价结果对比表明该评价方法更接近实际建筑物损害状况。

Based on grey correlation model of grey theory, it is selected 3 surface deformation factors of horizontal deformation, curvature deformation and slope deformation which cause buildings damage. The grey correlation evaluation model of buildings was established. In accordance with the principle of relevance, the correlation degree of the evaluation criteria was determined by combining the weight of each factor. Compared with the traditional evaluation method, this method is used to evaluate the internal factors of building damage, and the traditional evaluation is static building. The results show that the gray correlation model is more objective and scientific to evaluate the damage of the buildings.
