英国伦敦帝国理工学院作为工程与物理科学研究委员会（EPSRC）资助的研究项目的一部分，与Crossrail城市铁路项目合作，正在进行实地监测研究，以调查隧道开采对现有隧道的影响。在海德公园和贝斯沃特路附近安装了综合仪器，在贝斯沃特路下面的伦敦粘土中建造了新的Crossrail隧道，位于现有的伦敦地铁中心线隧道之下。在横贯铁路隧道线路周围安装了地面和地下仪器，以监测隧道施工对地面的反应。采用足够分辨率和精度的监测系统，获得高质量的数据，用于评估土压平衡机掘进引起的地面响应和移动机制。地面和地下仪器的安装工作于2011年夏天进行。本文对该系统的安装进行了描述和讨论。
Imperial College in London, UK, as part of an Engineering and Physical Sciences Research Council (EPSRC) funded research project and in collaboration with Crossrail urban railway project, is performing field monitoring research to investigate how tunnelling affects existing tunnels. Comprehensive instrumentation was installed in Hyde Park and bordering Bayswater Road, beneath which the new Crossrail tunnels were constructed in London Clay below the existing London Underground Central Line tunnels. Surface and subsurface instruments were installed around the Crossrail tunnel alignments to monitor the ground response to the tunnel construction. Monitoring systems of sufficient resolution and accuracy were adopted to achieve high-quality data for assessing the tunnelling-induced ground response and mechanisms of movement from earth-pressure-balance machine tunnelling. The installation of surface and subsurface instrumentation took place in the summer of 2011. This paper describes and discusses the installati...
