This paper describes the interaction of the Crossrail project to deliver London's new Elizabeth line in the UK with a building situated directly over the machine-bored tunnels, close to Paddington station. The initial scheme called for the demolition of the existing building at 4–18 Bishop's Bridge Road, including extraction of existing piles, which would have had a considerable impact on the local area. Changes in the design of the Elizabeth line station at Paddington allowed a revised strategy to be considered, whereby the building could be kept, reducing construction costs to the project considerably. A combination of desk study and ground investigation works was used to identify the likely extent of the piling under the building, and to predict the risk of clashes with the tunnels. The results of analyses considering the impact of construction works on the building, and associated monitoring results are presented. The decision not to demolish produced numerous benefits aside from the reduction in cost, including a considerably reduced impact on those using the building and adjacent areas.

Crossrail项目：4-18 Bishop的桥路对英国伦敦新伊丽莎白线的影响

本文描述了Crossrail项目与英国伦敦的新伊丽莎白线之间的交互作用，该建筑物直接位于机加工隧道上方，靠近帕丁顿车站。最初的计划要求拆除毕晓普桥路4-18号的现有建筑物，包括拆除现有的桩，这会对当地产生重大影响。帕丁顿（Paddington）伊丽莎白（Elizabeth）线车站设计的变化允许考虑修订的策略，从而可以保留建筑物，从而大大降低了项目的建设成本。案头研究和地面调查工作相结合，用于确定建筑物下方打桩的可能程度，并预测与隧道发生碰撞的风险。给出了考虑到建筑工程对建筑物的影响的分析结果，以及相关的监测结果。除了降低成本外，不拆除的决定还带来了许多好处，包括大大减少了对使用建筑物和邻近区域的人的影响。
