改进的 Maksimovic 峰值剪切强度准则的试验验证
Experimental validation of modified Maksimovic peak shear strength criterion for rock fractures
摘要
Abstract
The original Maksimovic peak shear strength criterion, has a concise form and clear physical meaning of the used parameters; but it cannot be used as a predictive tool to assess the peak shear strength of rock joints, because the roughness angleD , which reflected the roughness of joint surface, is determined by back analysis according to the experimental results. The modified one inherits all the merits of the original criterion and the roughness angle is determined by a quantified roughness metric. In the current study, the modified Maksimovic criterion is validated using experimental data of rock joints. The good agreement between the calculated values and the measured ones indicates that the modified one has the ability to evaluate the peak shear strength for rock joints.关键词
