偏心观测在多站式自动化监测中的应用
|
摘要
在市政道路建设中,由于道路建设基坑开挖必然对其下方及周边的地铁隧道稳定与安全造成影响,因此对与施工道路共线区域的地铁隧道进行实时监测是维持地铁安全运营,保证施工顺利进行必不可少的条件。本文以深圳市某快速路与地铁11号线共线监测区域长度约1000m的2标为例,针对目前地铁隧道监测范围一般在200m以内居多,超长监测范围监测范围内的多台仪器不能直接与基准点通视的经验较少的现状,提出偏心观测的多站式自动化监测系统,对地铁隧道进行高精度的实时全程监测。结果表明使用此监测方法有效指导了基坑施工,为深圳地区基坑开挖对既有地铁隧道超长影响范围的监测积累工程经验,为今后类似工程的变形监测提供参考。
This paper takes the 2 standards of the length of the monitoring area of a certain expressway and Metro Line 11 in Shenzhen as an example,aiming at the current situation that the monitoring range of metro tunnel is generally less than 200 meters,and the experience that many instruments within the monitoring range of super-long monitoring range can not directly communicate with the reference point is less,puts forward a new method based on bias.The multi-station automatic monitoring system for heart observation is used to monitor the metro tunnel in real time with high accuracy.The results show that this monitoring method can effectively guide the construction of foundation pit,accumulate engineering experience for monitoring the influence of foundation pit excavation on the super-long range of existing metro tunnels in Shenzhen area,and provide reference for deformation monitoring of similar projects in the future.
