摘要
拟建的凤潭隧道工程上穿既有输水隧洞,小净距、地质条件复杂,安全风险高。通过导硐法和单侧壁导坑法施工,最终顺利完成隧道爆破开挖。工程实践表明:爆破效果较好,有效控制了爆破振动。文中总结的爆破管理经验对其他隧道爆破工程有一定参考作用。
The proposed Fengtan Tunnel Project up-traversing the existing water-conveyance tunnel in small spacing. The tunnel is complex in geo-logical conditions and high risky in safety. Despite all that, through advance bottom heading, single side drift tunneling method, successfully completed the tunnel blasting excavation. The engineering practice shows that the effect of the blasting is good, the project is effectively controlling the harm of blasting vibration. Blasting management experiences summarized can be used for reference to blasting management of other tunnels.
