The Southbank Place project comprised the redevelopment of the UK headquarters of the Shell Company (formerly known as the Shell Centre) in the Waterloo area of London. The project included the demolition of all structures within the site except for the iconic tower building, local extension of the existing basement and the construction of eight new mixed-use buildings. London Underground's (LU) Bakerloo Line and Northern Line running tunnels pass beneath the site. The excavation of the basement and construction of the Shell Centre in the late 1950s caused movements of the underlying Bakerloo Line tunnels that were much larger than expected. The monitoring of these tunnels between 1958 and 1995 has provided a classic case history for the behaviour of London Clay. The proposed redevelopment offered an opportunity to analyse and monitor the behaviour of LU tunnels over a period of 60 years and two phases of significant construction. This paper presents a back-analysis of the historical monitoring of the Bakerloo Line tunnels and the calibration of a sophisticated finite-element model. The model was subsequently used to predict the impact of the redevelopment on the tunnels as part of the assurance procedure with LU.

Southbank Place 开发：隧道移动预测和监控性能

南岸广场项目包括位于伦敦滑铁卢地区的壳牌公司英国总部（前身为壳牌中心）的重建。该项目包括拆除场地内除标志性塔楼外的所有建筑物、现有地下室的局部扩建以及建造八座新的混合用途建筑。伦敦地铁 (LU) 贝克卢线和北线运行隧道从该站点下方穿过。 20 世纪 50 年代末，地下室的挖掘和壳牌中心的建设导致贝克卢线地下隧道的移动量远大于预期。 1958年至1995年间对这些隧道的监测为伦敦克莱的行为提供了经典的案例历史。拟议的重建提供了一个机会来分析和监测 LU 隧道在 60 年期间和两个重要建设阶段的行为。本文对贝克卢线隧道的历史监测进行了回溯分析，并对复杂的有限元模型进行了校准。该模型随后被用来预测重建对隧道的影响，作为 LU 保证程序的一部分。
