| 摘 要： | 隧洞是建筑物引水系统的重要组成部分，地下隧洞开挖后深部围岩应力场的状态变化对预测围岩失稳和开裂具有十分重要的意义。本文讨论了围岩应力分析中的本构模型和围岩应力分析中M－C准则的应用，用RFPA软件对隧洞开挖过程中围岩的应力场分布进行了相关的数值模拟，很好地验证了理论上的一些结论。

| Abstract: | The hydraulic tunnel is an important component of the building system. After the underground tunnel is excavated, the change of stress field of the surrounding rocks is significant for forecasting jitter and the dehiscence of the surrounding rocks. This article discusses the construction model and application of the M-C criterion in the stress analysis of the surrounding rocks. RFPA can be used in simulating the stress change in the surrounding rocks to testify some theoretical conclusions. |
