摘要
本文主要研究紧邻既有建筑隧道爆破掘进施工控制技术,重点探讨了减振措施的应用。首先介绍了减振措施的重要性,然后分别从降低循环进尺、隧道周边预切槽减振技术、预裂爆破减振技术、隔断桩隔震技术、大直径中空掏槽眼和微差起爆网路等方面详细阐述了减振措施的具体实施方法和效果。最后,通过实验验证了减振措施的有效性,并提出了未来研究方向。
This article mainly studies the construction control technology of blasting excavation in adjacent existing building tunnels,with a focus on exploring the application of vibration reduction measures.Firstly,the importance of vibration reduction measures was introduced,and then the specific implementation methods and effects of vibration reduction measures were elaborated in detail from the aspects of reducing cyclic footage,pre cutting groove vibration reduction technology around the tunnel,pre cracking blasting vibration reduction technology,isolation pile isolation technology,large-diameter hollow cut hole,and micro difference blasting network.Finally,the effectiveness of vibration reduction measures was verified through experiments,and future research directions were proposed.
