路堑开挖钻孔爆破施工

Drilling and blasting construction in cutting excavation

结合工程概况,对该工程的施工方案进行了选定,从深孔爆破、光面爆破、预裂爆破等方面对其施工方法进行了论述,并对路堑爆破施工安全措施和质量控制方面进行了阐述,在现场施工中的应用表明,该施工方案对施工组织和边坡控制均达到了预期的效果。

Combined with practical engineering, the author determines the construction scheme of this engineering, discusses its construction methods from deep hole blasting, smooth blasting and pre-splitting blasting, illustrates construction safety and quality control of cutting blast- ing, and shows by application in field construction that the construction scheme achieves the expected results of construction organization and slope control.
