针对土木工程专业大多数本科生未能透彻理解摩尔-库伦强度理论的现状，提出采用伺服控制系统进行加载和卸载条件下岩石的应力应变全过程实验，而后建立三维数值模型模拟实验曲线，并以动画形式展现试样在受力过程中剪切面的形成及其贯通。实验教改成果对学生全面掌握摩尔-库伦强度理论实质，增强实验兴趣，提高对课程的认知能力，以及拓展数值分析知识水平等都具有重要意义。

An education reform on rock triaxial compression experiment was presented because many undergraduates can not well understand the theory of Mohr-Column. In this reform, a whole procedure stress and strain experiment under loading and unloading was carried out. A three-dimensional numerical model was established to simulate the experimental curves. An animation based on numerical analysis was made to vividly show the form and cut-through of shear band in the rock sample. The reform results are of important significances for undergraduates to comprehensively understand the theory of Mohr-Column, enhance the interests to do experiment, improve the understanding of the theory, and develop the knowledge of numerical analysis.
