| 摘 要： | 根据在重庆陆家岭隧道施工中发生的岩爆,通过现场地质观测资料,具体地分析了其形成的规模、位置、诱发因素以及地质条件,从地质工程的角度,对岩爆发生地段隧道的岩石组成、地质构造、地应力特征以及地下水情况进行了探讨,发现在陆家岭隧道施工中发生岩爆的岩石具有岩体结构面发育适中、弹性模量大、P波波速高、地质构造简单、现代水平构造应力强且主压应力轴σ1大角度相交于隧道中轴线和地下水不发育的特征,并在此基础上,提出了掌子面喷水、布设释放地应力锚杆、减少隧道壁聚能结构等有效的岩爆防治措施。

| Abstract: | The geological characters of rockburst in Lujialing tunnel depending on the data summarized with geological observation during tunneling are studied,and the rockburst qualities including scale position and geological conditions are analyzed. Then the mainly control factors of the rockburst which consists of rock-form, geological structure,geo-stress and groundwater have been discussed from the viewpoint of geological engineering. Finally,the prevention methods in accordance with geological qualification in Lujialing tunnel have been presented. |
