摘要(Abstract)：

隧道是铁路等交通设施的重要组成部分，研究隧道爆破开挖过程中的振动响应和衰减规律对隧道建设具有重要意义。以渝昆高铁线路建设为背景，研究了高铁隧道爆破开挖时面临极小净距问题的爆破方案，提出了将掘进断面分为左右两侧交替爆破的开挖方式，并对双线隧道进行了爆破振动速度监测。对先行洞振动速度分析表明：隧道内最大振动速度主要由掏槽孔及拱顶辅助孔爆破产生，并且径向振动速度最大；横断面上，迎爆侧边墙拱腰振速为拱脚振速的1.3倍至2倍，且由掏槽孔起爆引起的该振速倍率相对较小；纵断面上，掌子面前方各测点振动速度大于后方相对位置处振速，而后方振速衰减速率相对更高。研究结果已成功应用于现场工程实际，相关隧道小净距段已安全贯通，可对类似极小净距隧道工程提供一定的借鉴参考意义。
