近年来,经济发达城市的地铁工程建设日趋普遍,许多商业城市已经实现了地铁的运行或者正在建设城市地铁。地铁工程在建设及运营的过程中受到内部和外界因素的影响,存在着许多安全、质量问题,若不及时处理会造成地铁交通线路中断,对隧道结构和运营安全十分不利,对城市现代化发展不利。为确保工程施工过程中地铁结构及附属设施的绝对安全,必须对地铁结构及附属设施进行保护监测。本文简要论述采取合理的地铁隧道监测技术,对于保证地铁的安全运行具有重要的意义以及地铁隧道监测的一些重点项目和注意事项。
In recent years, the construction of subway projects in economically developed cities is becoming more and more common. Many commercial cities have already realized the operation of subways or are constructing urban subways. Subway projects are affected by internal and external factors during construction and operation. There are many safety and quality problems. If they are not dealt with promptly, they will cause disruptions to the subway lines and adversely affect the urban structure and operation, adversely affecting the modernization of urban areas . In order to ensure the absolute safety of the subway structure and ancillary facilities during the construction, the subway structure and ancillary facilities must be protected and monitored. This paper briefly discusses the reasonable metro tunnel monitoring technology, which is of great significance to ensure the safe operation of the subway as well as some key projects and precautions of subway tunnel monitoring.
