Maksimovic 峰值剪切强度准则形式简洁，参数的物理含义明确，但由于反映节理粗糙程度的特征量“粗糙度角jD”须由试验值确定，因此不可用于估算岩石节理的峰值剪切强度。改进的 Maksimovic 峰值剪切强度准则在继承原准则优点的基础上，采用定量化的三维形貌参数表示节理的“粗糙度角jD”。采用岩石节理的直剪切试验数据对改进的 Maksimovic 峰值剪切强度准则进行了试验验证，计算值与试验值具有很好的相关性，表明可以采用该准则估算岩石节理的峰值剪切强度。

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.
