During the course of numerical computation and stability evaluation on the jointed rock masses engineering, the determination of strength parameters is very important. 摘要在节理岩体工程的数值计算及稳定性评价中，强度参数的确定至关重要。
Fast lagrangian analysis of continua method was employed to simulate the distribution of internal stress, the change of displacement and the course of slope instability. 而强度折减法对开挖前后边坡的稳定性评价结果也表明路堑开挖是该边坡失稳的主要原因。
