经历5年时间建设，随着一声爆破巨响，属川藏铁路拉萨至林芝段重点控制性工程的巴玉隧道，上周六（2日）上午9时50分正式贯通。该隧道属川藏铁路第3条贯通的10公里以上特长隧道，为川藏铁路拉萨至林芝段2021年通车，打下坚实基础。

巴玉隧道连接西藏山南市加查县和曲松县，沿雅鲁藏布江大峡谷江边而建，全长逾13公里，最高海拔约达3500米，最大埋深2080米，其中94%位于岩爆区。“岩爆”是一种复杂的动力型地质灾害，在开挖或其他外界扰动时，岩石会爆裂并弹射出来，直接威胁施工人员和设备的安全。

巴玉隧道在施工过程中曾多次发生岩爆，单次最长持续时间超过40小时，是世界隧道施工史上罕见。在施工过程中，施工人员还要克服高地温、通风排烟困难等问题。
