以实际工程为依托,针对Ⅴ级软弱破碎围岩中重载浅埋隧道的特点进行施工方案的分析,以及针对施工过程中保护措施的技术要点进行了分析与讨论,论证了其安全施工措施的可行性,并通过其监测内容及监测结果的实时分析与反馈,为隧道安全施工提供了依据。长期监控量测结果表明,该隧道处理措施是安全可行的,达到了围岩与支护结构体系安全与稳定的要求,所采用的安全施工措施以及信息化施工方法对类似工程具有指导和借鉴意义。
Based on the actual project, the construction scheme is analyzed according to the characteristics of heavy-duty shallow tunnel in Grade V weak broken rock and the technical points for the protection measures during the construction are analyzed and discussed. The safety construction measures Feasibility and through the real-time analysis and feedback of its monitoring content and monitoring results provide the basis for the construction of tunnel safety. The results of long-term monitoring measurements show that the tunnel treatment measures are safe and feasible, and meet the requirements of safety and stability of surrounding rock and support structure system. The safe construction measures and information construction methods have guidance and reference for similar projects .
