| 淺埋隧道控制爆破施工技術(shù)(51 卷) |
| 英文標(biāo)題 |
| Controlled blasting technology used in shallow buried tunnel |
| 摘要 |
| 渝利鐵路火風(fēng)山淺埋隧道采用爆破施工。通過利用爆破振動(dòng)監(jiān)測(cè)及聲波檢測(cè)技術(shù)，結(jié)合現(xiàn)場(chǎng)試驗(yàn)數(shù)據(jù)，分析了毫秒導(dǎo)爆管雷管爆破對(duì)地表及基樁底部的振動(dòng)和圍巖損傷的影響。結(jié)果表明：采用電子雷管后距離掌子面20 m的最大爆破振動(dòng)速度降為2 cm/s以下，地表振動(dòng)速度為0 |
