摘　　要：环境量因子之间存在的相关性直接影响大坝安全监测统计分析的结果。基于某混凝土拱坝实测变形资料,采用差值统计分析方法对因子间的相关影响进行消除,并与常规逐步回归分析方法进行了对比。结果表明,差值统计分析在自动化监测采集条件下可达到逐步回归的精度并保证统计分析的可靠性。The existence of correlation among environment factors affects the result of dam safety monitoring statistical data analysis. Basing on a arch concrete dam measured deformation data, statistical analysis of the difference methods is used to eliminate the correlation among impact factors, and the conventional stepwise regression analysis methods are compared. The result shows that statistical analysis of the difference methods can achieve the precision of stepwise regression statistical analysis under the automated monitoring acquisition conditions, while guaranteeing the reliability of statistical analysis.
