摘　　要：主要介绍对逐步回归分析模型的原理和基本步骤,结合大坝工程实例进行分析。引入了库水位、时效和温度三个因子建立逐步回归模型。得出了运用逐步回归模型分析大坝变形的合理性,可以达到预测的目的。This paper mainly introduced to the basic principle and the basic steps of stepwise regression analysis mode, and combined with the dam project analysis example. Bring in the library of water level time and temperature three factors establish regression model. By using the regression model analyzed of the dam deformation were rationality, can achieve the purpose of prediction.
