摘　　要：岩爆是地下工程建设过程中常见的一种地质灾害现象。结合国内外部分工程岩爆发生的实际情况,分析了影响岩爆的主要因素和部分特征。并通过对齐热哈塔尔引水隧洞支洞施工过程中岩爆的发生特征分析,对引水隧洞主洞的岩爆发生情况进行了预测。结果表明,工程施工过程中要不断认识和总结岩爆的发生规律将更有利于岩爆的预测与预防。Rock burst is a common geology hazard in underground construction. Combined with the actual rock burst practice at home and abroad, the main factors and some characteristics of rock burst are analyzed. According to analysis on characters of rock burst of Qirehataer diversion tunnel, the rock burst condition of main tunnel of diversion tunnel is predicted. The results show that constant recognition and summarization on occurrence regularity of rock burst in the process of construction is very important, and it is beneficial for rock burst prediction and prevention.
