摘要
采用脆性破坏统计理论研究结构性土体的损伤性质 ,提出了应用土体强度关于Weibull分布的分析方法得到了结构性土体的宏观损伤演化方程和本构模型 .根据损伤容限定义了稳定安全系数 .
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.
