摘要
针对工程建筑物变形中存在的变形因素复杂、变形大小不确定性、点位间主次关系不明确等情形,将灰色系统中的多维GM(1,N)模型引入到工程建筑物变形监测分析中进行多点分析,研究工程建筑物的变形规律,合理预测未来的变形趋势。利用关联分析方法确定有效因子,综合分析系统受不同监测点影响的因素,通过工程实例进行了分析、建模和验证,建立了相应的GM(1,2)或GM(1,3)模型,提高了模型精度,为工程建筑变形分析提供了有效的分析方法和手段。
Due to the complex of deformation factors, the uncertainty of deformation amount and the unknown of primary and secondary relationship between the points in the deformation of buildings, GM （1, N） model is introduced and a multi-point analysis was carried out to analyze the deformation of buildings and predict future tendency of the deformation reasonably. A correlation analysis method is used to determine the effective factors, establish the GM （1, 2） or GM （1, 3） models and improve the precision of the model by comprehensively analyzing the influence of the monitoring system. This study provides a useful and valid method for the deformation analysis of buildings in practical engineering through analysis and modeling.
