| 摘 要： | 西山隧道古交端出口正洞围岩为水平状石灰岩,层面和节理裂隙发育,隧道爆破开挖后,拱部岩体掉落的现象非常普遍。通过采取调整爆破参数等方法,减少了对围岩的扰动,显著减小了超挖数量,确保了施工安全,提高了施工进度,并取得了良好的经济效益。

| Abstract: | The rock of the main tunnel in Gujiao export terminal of Xishan Tunnel is level shape limestone,level and joint fissures is in growth.After blasting the tunnel,the arch rock falling is very common.By adjusting the blasting parameters and other methods,it reduced the disturbance of rock,significantly reduced the number of super-digging,ensured the construction safety and improved the construction schedule,and achieved good economic results. |
