摘要:
以甘肃省甘南藏族自治州夏河隧道为研究背景，对高海拔环境下山岭隧道微振控制爆破技术进行了研究，以降低爆破振动对周边环境的影响。分析总结了导致原方案振动强度大的主要问题，对爆破参数进行优化调整。通过缩短掘进尺、改用小直径中空直孔掏槽形式，调整炮孔布置及各项参数，引入数码电子雷管精细设计，最后形成适用于夏河隧道的小台阶、短进尺、毫秒延期微振控制爆破方案。结果表明：爆破效果良好，振速控制在0.5 cm/s以内。提出的微振控制爆破技术能够实现有害效应控制，为复杂环境下隧道施工提供参考。
Abstract:
During the excavation of Xiahe Tunnel in Gannan Tibetan Autonomous Prefecture, Gansu Province, the micro-vibration controlled blasting technology of mountain tunnel in high altitude environment was studied to reduce the impact of blasting vibration on the surrounding environment. The main problems causing the high vibration intensity of the original scheme were analyzed and summarized, and the blasting parameters were optimized and adjusted. By shortening the driving footage, changing the small-diameter hollow straight hole cutting form, adjusting the blast holes layout and various parameters, applying the digital electronic detonator, a small bench, short footage, millisecond delay and micro-vibration control blasting scheme suitable for the construction of Xiahe Tunnel was finally formed. The field tests show that the blasting outcome is excellent, and the vibration velocity could be controlled within 0.5 cm/s. The blasting technology proposed not only realizes the control of negative impacts, but also can provide reference for tunnel projects in the complex environment.
