摘要
岩爆是地下工程掘进过程中所遇到的一种动力地质灾害,极大地威胁着施工人员和设备的安全。论述了岩爆的定义、特征及作用机理。结合国内外相关岩爆判据判定和理论分析,通过有限元数值模拟,对西华岭隧道开挖中是否会产生岩爆等施工地质灾害做出了最终的判定。
Rockburst is a serious geologic hazard that endangers greatly the security of operators and facilities involved in the production. The definition of rock explosion with its occurring laws of nature, its character is discussed. With the criterion for rock burst and some thoerotical analysis, through numerical simulation software, the conclusion upwards is also validated.
