| Abstract: | The damage mechanism of cemented soil was studied by the brittle failure statistical theory. A damage evolution equation and the constitutive model of cemented soil were obtained by the method of Weibull distribution about soil strength. The safety coefficient for soil structure was defined in accordance with damage tolerance limit. The analysis of slope stability of excavating and loading showed mechanism of retrogressive and propellant slide. |

| Keywords: | cemented soil damage Weibull distribution damage tolerance limit damage variable monitoring |
