This paper describes the redevelopment of Calder's Wharf, London, a four-storey block of residential units. As part of this redevelopment a detailed finite-element and ground movement analysis was undertaken to establish the potential impact of the proposed structure on two Docklands Light Railway (DLR) tunnels that run directly below the site and beneath the footprint of the proposed development. The case study presents the as-constructed displacements within the tunnel lining and compares these real-time measurements with the predictive models used in the engineering design. The analysis indicated that stress changes over the long term on the tunnel linings were of the order of 5 kPa maximum. This is equivalent to an increase in depth of the tunnel of 0.25 m and was not considered to be material to the tunnel.

Calder's Wharf 开发对英国伦敦 Docklands 轻轨隧道的影响

本文描述了伦敦考尔德码头的重建，这是一座四层高的住宅单元。作为本次重建的一部分，进行了详细的有限元和地面运动分析，以确定拟议结构对直接在场地下方和拟议开发足迹下方运行的两条 Docklands 轻轨 (DLR) 隧道的潜在影响。案例研究展示了隧道衬砌内的施工位移，并将这些实时测量结果与工程设计中使用的预测模型进行了比较。分析表明，隧道衬砌长期的应力变化最大为 5 kPa 的数量级。这相当于隧道深度增加了 0.25 m，并且不被认为是隧道的材料。
