Abstract

Abstract: As one of the geological hazards, rockburst is often met in underground engineering under excavation unloading conditions of high geostress areas. According to the actual mechanics conditions, the triaxial test is designed to simulate the excavation of tunnel in this paper. The deformation-failure characters are elaborated. These results can play important roles in the mechanics mechanism of rockburst.

Key words: rockburst, triax ial test under unloading condition, deformation failure character

摘要： 岩爆是高地应力区地下工程中常见的一种开挖卸荷施工地质灾害现象.笔者按照地下工程洞室开挖过程中围岩的实际受力状况,主要采用卸荷三轴试验方法,探讨了岩爆岩石的变形破坏特征问题,测试成果可为进一步正确分析研究岩爆形成的力学机制提供重要的实验依据.

关键词: 岩爆, 卸荷三轴试验, 变形破坏特征
