| 光面爆破技術(shù)在新武家莊隧道掘進(jìn)中的應(yīng)用(51 卷) |
| 英文標(biāo)題 |
| Application of smooth blasting in excavation of new Wujiazhuang tunnel |
| 摘要 |
| 昆明鐵路樞紐改造工程中的新武家莊隧道為大斷面軟弱圍巖隧道，爆破施工效果差。針對(duì)軟弱圍巖，采用分部開挖和光面爆破結(jié)合技術(shù)，進(jìn)行了爆破參數(shù)、炮眼布置、裝藥結(jié)構(gòu)優(yōu)化設(shè)計(jì)，取得了較好的爆破效果。該方法施工簡單、安全經(jīng)濟(jì)，對(duì)同類隧道工程施工具有一定的借鑒意義。 |
