基于现场监测的务西作隧道预警及稳定性分析
摘要:隧道监控量测是新奥法三大核心之一,已成为隧道施工中一个不可缺少的因素。对评价隧道施工方法的可行性、设计参数的合理性,了解隧道施工实际围岩级别及其变形特性等能够提供准确、及时的依据。为了确保隧道顺利安全的进行施工,通过对务西作隧道浅埋偏压段测量的拱顶沉降、周边收敛、地表沉降的数据进行分析整理,并及时预警,之后施工方及时采用临时仰拱和加密钢拱架进行加固,使得围岩稳定,防止了坍塌的隐患。研究分析的结果及处理措施可以为以后类似的工程提供参考。
Abstract:Tunnel monitoring,being the core of New Austrian Tunneling Method,has become an essential factor in the construction of the tunnel.It provides accurate and timely basis for evaluating the feasibility of construction method,the rationality of design parameters and understanding of the actual level of surrounding rock and its deformation characteristics.In order to ensure the safety of the tunnel construction,the data of vault subsidence,peripheral convergence,and the surface subsidence were analyzed for the Wuxizuo shallow bias tunnel section,and timely warning of the hidden risk was proposed after that the reinforcement measure of the temporary inverted arch and encryption steel arch was taken timely to.secure the stability of surrounding rock and prevent the hidden danger of collapse.The result of analysis and treatment measures provide reference for similar projects.
