摘要

伦敦银行站安装了新的地下三层自动扶梯，这是一项重大容量升级项目的一部分。不同寻常的是，由于通道受限，倾斜的挖掘机隧道是上山而不是下坡开挖的。使用喷射混凝土衬里，没有先导隧道，这是英国第一个三层自动扶梯。新的自动扶梯拦截了几个现有的结构，这些结构必须进行回填，然后再进行拆除，其中一些距离运营的地铁线只有0.5米。本文阐述了设计考虑、施工顺序决策、操作风险管理，并在综合监测方案的基础上讨论了现有资产对上坡隧道施工的反应。

Uphill excavation of an escalator barrel between operational underground platforms

A new underground triple escalator has been provided at Bank Station in London as part of a major capacity upgrade project. Unusually the inclined excavator tunnel was excavated uphill rather than downhill due restricted access. Using a sprayed concrete lining and no pilot tunnel, it was a first in the UK for a triple escalator. The new escalator intercepted several existing structures which had to be backfilled and then broken out, some just 0.5 m from operational Tube lines. This paper sets out design considerations, construction sequence decisions, operational risk management and discusses the existing assets’ response to uphill tunnelling based on a comprehensive monitoring scheme.

期刊介绍： Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues. Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to. Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community. It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
