山岭隧道钻爆法施工坍塌风险及围岩稳定性分析研究

Analysis and Research on Collapse Risk and Surrounding Rock Stability During Drilling and Blasting Construction of Mountain Tunnel

随着道路工程的发展,隧道工程越来越多。然而其施工方法的好坏直接决定着隧道建设整体的经济效益、施工进度、围岩支护安全和运营期安全。钻爆法是隧道施工中最常用的施工方法之一。钻爆法施工受围岩条件、爆破参数选择、采用装药方式、爆破器材选择等施工方法影响。

With the development of road and railway engineering,tunnel engineering is becoming more and more.However,the quality of its construction method directly determines the overall economic benefits,construction progress,surrounding rock support safety and operation period safety of tunnel construction.Drilling and blasting method is one of the most commonly used construction methods in tunnel construction.Drilling and blasting construction is affected by surrounding rock conditions,blasting parameters,charging method and blasting equipment Construction methods such as selection.
