| 摘 要： | 针对传统变形监控模型分析和解决变量间相关性的不足，借助因子分析法通过寻求变量的公共因子，概括出相互独立的影响因子，得出影响大坝变形的主要因素及其影响程度。实例分析结果表明，因子分析模型处理监测数据的相关性较传统模型有一定优势，更大限度地解释了原始数据信息。

| Abstract: | Traditional model of deformation monitoring has shortcomings for analysis of the correlation between variables. Factor analysis method is used to find the common factor variables. And the independent impact factor is summed up. Then the main factors and corresponding influence on dam deformation are obtained. Example results show that the proposed model has some advantages in dealing with the relevance of monitoring data and it can better explain the information of original data. |
