中文摘要：

利用连续损伤理论和统计强度理论，建立了完整模拟岩石破裂全过程的损伤统计本构模型。在所建立的损伤统计本构模型的基本方程中，引入岩石应力应变全过程曲线特征参量，并考虑岩石应力应变全过程曲线的几何条件，解决了传统方法求解本构方程中参数的难点，同时提高了精度。基于取自某边坡工程的砂岩所进行的三轴压缩试验实测结果，对所建立的岩石损伤统计本构模型进行了验证，验证了所建的模型是合理的。

英文摘要：

Based on continuum damage theory and statistical strength theory, this paper presents a statistical damage constitutive model reflecting the full process of rock failure, in the fundamental equations of which the characteristic parameters of complete stress - strain curves of rock failure are introduced and the geometrical characteristics of the curves are considered also, so as to solve the difficulties in resolving the parameters of the constitutive equation by traditional method and increase the precision of solutions. Finally, based on the results obtained by triaxial compression test of sandstone from some side slope, this article validates the established statistical damage constitutive model for rock is reasonable.
