摘要
暗挖隧道爆破开挖施工过程中,保持良好的开挖质量,无论从成本控制角度还是工期角度,都具有重要的意义。以深圳地铁8号线望基湖停车场入场线隧道为例,对影响隧道开挖质量的条件展开分析,通过运用光面爆破技术以及加强现场施工质量管理等手段,最大程度的减少超欠挖,有效的提升了隧道的开挖质量,可为同类隧道开挖施工提供借鉴。
In the process of blasting excavation,it is of great significance to maintain a good excavation quality in terms of cost control and time limit.Taking Wangjihu parking lot entrance line tunnel of Shenzhen metro line 8 as an example,this paper analyses the conditions affecting the quality of tunnel excavation.By using smooth blasting technology and strengthening the quality management of site construction,it can minimize overbreak and underbreak,effectively improve the quality of tunnel excavation,and provide reference for similar tunnel excavation construction.
