摘要：

Based on the analysis of the influencing factors and the statistic model of stress-strain, the multiple factors time-varying monitoring model for dam concrete stress-strain is established, in which the multilayer hierarchical and regression analysis methods are combined. Time-varying parameters are calculated based on the new factors which are obtained from the product of the regression coefficients and old factors. In the model, the function of the higher stability correlation factors are strengthened, so as to improve prediction precision of the model.
