| 中文摘要:结合工程实例，基于块体的失稳条件和层状岩体的破坏条件，分析不同地质构造形态岩层下，隧洞开挖过程中围岩的稳定性。并根据洞室围岩产状与开挖几何边界的关系，提出围岩易破坏点的位置确定方法。最后，通过对工程实例中围岩塌方的统计，分析塌方围岩原因，进一步验证层状岩体中围岩的稳定性评价。 |

| Abstract:According to the unstable condition of the displaceable block and the breakage term of the stratified rock, this paper analyzed the stability of surrounding rock during the excavating process in different geological structures. And according to the relation between rock occurrence of the underground chamber and geometrical boundary of excavation, the paper gave the method to positioning breakage. Finally, by the analysis on the cause of collapse in engineering, evaluation on stability of surrounding rock in stratified rock was further tested. |
