| 摘 要： | 考虑岩石节理变形的非线性特性，提出了一种新的节理模型，不仅能表现塑性剪切变形和剪胀，而且也能考虑法向应力引起的张裂与闭合时的非线性变形特性．这种模型可用于地下工程和边坡的稳定性分析及渗流与应力的耦合分析．

| Abstract: | Considering the non linear deformation character of rock joints, a new non linear constitute model of rock joints,which can describe the opening/closure and shear characteristics of joints,has been derived from the mathematical theory of plasticity.This model is useful for stability or hydromechanical coupling analysis of slopes or underground excavations by FEM. |

| Keywords: | joint constitute model opening/closure yield criterion flow rule |
