这篇文章提供了介绍性的材料，涵盖了关于城市地区机械化隧道施工的重要问题。作者列举了在这些条件下开挖的一些危险，如：地面和地下设施，人造地面，密集的地面基础设施，混合地质，恶劣的地面条件，浅覆盖层，地面沉降，以及地下水的存在。此外，作者还为这些项目提供了四条指导方针作为提纲。这些措施首先是尽量减少对地面的滋扰，为所有污水系统和上层建筑提供设施，避免隧道工作面坍塌，以及小心注意地面沉降的规格限制。作者还讨论了国际上对风险管理和城市环境整体挖掘的关注的必要性，提供了他们所撰写的主题的全书处理的大纲，并以他们的风险管理计划(RMP)作为其方法的关键组成部分的描述结束。
This article provides introductory material covering important issues regarding mechanized tunneling for urban areas in particular. The authors list a number of hazards with excavating in these conditions, such as: surface and subsurface utilities, man-made ground, dense surface infrastructure, mixed geologies, poor ground conditions, shallow overburden, ground settlements, and the presence of groundwater among them. Additionally, the authors provide four guidelines for these projects as an outline. These are first to minimize disturbances to the surface, provide for all sewage systems and super structures, avoid the collapse of the tunnel face, and carefully mind limitations of the specifications of the surface settlement. The authors also discuss the need for increased international focus on risk management and overall excavation in urban settings, provide an outline for a book-length treatment of the subject that they have authored, and close with a description of their Risk Management Plan (RMP) as a key component of their methodology.
