摘    要:通过对隧道进行监控量测,可预测预报围岩变化,优化设计和指导施工,确保隧道施工安全,使工程投资经济合理.对济邵高速公路乔庄隧道的拱项下沉、水平收敛、地表沉降、喷层应力、钢拱架应力等多项涉及围岩稳定性及支护合理与否的参数进行跟踪量测.量测结果表明:隧道开挖及初期支护30d左右,围岩基本上趋于稳定,应按照规范要求及时施作二次衬砌:隧道洞口的地表基本没有沉降,说明浅埋段采用管棚注浆技术是适宜的.通过采取有效的监控措施,及时的指导施工和修改设计,成功避免了施工中重大安全事故的发生,确保了隧道施工安全和质量,对隧道施工具有指导意义.

Abstract:Through monitoring and measuring tunnels,surrounding rock change predictions and optimal designs can be done and the construction can be carried out under guidance,so that the construction safety can be guaranteed and the engineering investment can be more reasonable.The monitor measuring of NATM was studied in the Qiaozhuang Tunnel in Jishao Express way.Based on some monitoring and measuring job such as subsidence displacement,convergence displacement,submergence of ground,the sprayed coatings stress,the s...
Keywords:highway tunnel  NATM  monitoring measurement technology
