摘要
岩爆对整个隧道的施工安全及工期,影响巨大。文章针对桑珠岭隧道岩爆的实际情况,根据岩爆的特点,通过综合分析,对岩爆强度进行预判,并确定了岩爆段施工流程,为从开始就防止岩爆的发生,现场采取了必要的措施,以确保隧道施工的顺利进行。
The Rock burst has a great impact on the construction safety and construction period of the entire tunnel.According to the actual situation of rock burst in Sangzhuling tunnel,according to the characteristics of Rock burst,through comprehensive analysis,the rock burst strength was pre-judged,and the construction process of Rock burst section was determined.In order to prevent the occurrence of Rock burst from the beginning,the necessary measures were taken to ensure the smooth construction of the tunnel.
