隧道收敛自动监测系统在公铁交叉施工中的应用分析

Application Analysis of Tunnel Convergence Automatic Monitoring System in Construction of Highway and Railway Crossing

针对郑万铁路某隧道上跨高速公路某隧道可能会导致其受压变形,产生一系列施工和运营安全等问题,提出一种新型隧道收敛自动监测系统,能够保障上跨、下穿施工期间高速公路隧道的安全,实时动态掌握施工对已运营高速公路的影响程度,同时,对其应用进行分析总结研究。

For Zhengzhou-Chongqing High-speed Railway crossed the tunnel on the highway,it caused the tunnel to deform under pressure,and created a series of problems of construction and operational safety issues,this paper presented a new convergent automatic monitoring system for tunnel convergence,which can guarantee the safety of the tunnel on the highway during the construction of overpass and underpass,and grasp the influence of the construction on the operating highway dynamically in real time.Meanwhile,its application was analyzed,summarized and studied,and extended to similar engineering projects.
