了解地面及其带来的具体岩土风险对于Crossrail的成功交付至关重要，Crossrail是一个耗资148亿英镑的项目，旨在提供横跨英国伦敦的伊丽莎白线东西铁路。本文特别关注中央隧道部分，描述了该方案的广泛地质背景以及最初认为的主要岩土工程危害。报告还通过选定的实例，进一步说明如何通过详细的案头研究、有针对性的实地调查和客户主导的全面解释性报告，更明确地界定这些危害构成的具体风险。然后在设计和交付期间制定适当的缓解措施，以消除这些风险或将其降低到可管理的水平。
Understanding the ground and the specific geotechnical risks it presented was critical for successful delivery of Crossrail, the £14·8 billion project to deliver the Elizabeth line east–west railway across London, UK. Focusing specifically on the central tunnelled section, this paper describes the broad geological setting of the scheme and what were initially perceived to be the key geotechnical hazards. It further describes, with selected examples, how through detailed desk studies, targeted ground investigations and comprehensive client-led interpretative reporting, the specific risks posed by these hazards were more clearly defined. Appropriate mitigation was then developed both during design and delivery to eliminate or reduce these risks to manageable levels.
