| Abstract: | The paper has made a multiple linear regression analysis of the five major factors that affect concrete crack-resistant performance indexes and obtained the correlations among the factors and the weight of each factor affecting the crack resistance indexes based on the Three Gorges dam concrete laboratory test results by introducing the multiple regression analysis principle and model and by applying the statistical analysis program SPSS as well. |
