楔块滑动判别是碎裂岩质边坡工程稳定性分析和加固方案选择的关键技术。提出楔块极限平衡状态时新的判别准则，通过研究楔块滑落过程及其极限平衡状态，得到不同条件下楔块滑落函数方程。基于试验结果分析，并与函数方程对比，提出与该曲线相吻合的二次函数关系式，分析了极限平衡状态下楔块的力学状态，深入讨论了结构面参数(方位、粗糙度系数JRC)对函数式中系数的影响。推导出滑块粗糙度系数 JRC 与结构面交角条件下β-α(倾斜角-旋转角)关系曲线，以此作为楔块滑动与否的判别准则，试验结果验证其具有有效性，具有在工程中推广应用前景。

The identification of wedge slipping is the key technology for the stability analysis of fractured rock slope and the selection of reinforcement plan.The new criterion is proposed for the wedge in limit equilibrium state.The process of wedge slipping and the limit equilibrium state of wedge are studied,and the function of wedge slipping under different conditions is obtained.The experimental result is analyzed and compared with the function.Then,the quadratic equation co-incided with the curve is proposed,and the mechanical state of the wedge under the limit equilib-rium is analyzed.The influences of structural surface parameter (orientation,j oint roughness co-efficient)on the coefficient of the function are discussed in depth.Theβ-α(dip angle-rotation an-gle)curve is derived,which is as the criterion of determining whether the wedge slips or not. The experimental results show that the method is effective,and should be generalized in some proj ects.
