Teaching Design of Stress Calculation Method for Surrounding Rock of Deep Tunnel with Circular Cross-Section in Course Entitled Rock Mechanics

摘要: 文章根据《岩石力学》课程中深埋圆形横断面隧道围岩应力计算方法的教学内容，对深埋隧道围岩塑性区和弹性区内应力及其分布特征进行了推导，给出了易于学生理解和掌握的深埋隧道围岩应力计算方法及其分布特征的教学组织和设计，并分析了影响隧道围岩塑性区的因素。通过对所设计的深埋隧道围岩应力计算方法的教学实践，达到了预期的教学效果。

Abstract: Based on the teaching contents of the stress calculation method for surrounding rock of deep tunnel with circular cross-section in the course entitled Rock Mechanics, the stress and its distribution characteristics in the plastic and elastic zones of tunnel surrounding rock are derived in this paper. Both the teaching design and organization for the calculation method and distribution characteristics of surrounding rock stress for deep tunnel, which are easy for undergraduates to understand and master, are proposed, and meanwhile the factors affecting the plastic zone of tunnel surrounding rock are also analyzed. By designing and practicing the teaching method for calculating the stress of surrounding rock of a deep tunnel with circular transect presented in this paper, the expected teaching objectives has been achieved.
