上台阶无预留核心土钻爆法机械集群隧道施工技术探究

Research on tunnel construction technology of mechanical cluster with drilling and blasting method without reserved core soil on upper step

基于工程案例,围绕施工操作组织模式、主要工程机械和人员配置状态,对上台阶无预留核心土钻爆法机械集群隧道施工技术进行系统梳理,并通过该技术的主要施工功效分析验证其工程应用价值。

Based on the engineering case,focusing on the construction operation organization mode,main construction machinery and personnel configuration status,this paper systematically combs,summarizes and expounds the construction technology of mechanical cluster tunnel with no reserved core soil,and verifies and reveals its engineering application value through the main construction function analysis of the technology.
