Introduction: tunnels in urban areas and the related challenges The opportunities The particular challenges of urban tunnelling The correct approach to success A brief history of mechanized tunnelling The scope of this book Initial risks: definition, analysis and management Basic definitions Sources of initial risk in mechanized urban tunneling Analysis and management of risks: the risk management plan Designing for the identified risk scenario Quantifying the risk of time and cost overruns at the design stage with the use of DAT Use of Plan for Advance of Tunnel (PAT) for controlling the residual risks Selection of tunnel alignment with low-level risks Introduction The general layout of an urban tunnel Alignment constraints and specific functional requirements Constraints and peculiar characteristics of the urban environment relevant to the selection of a tunnel route Starting and arrival points, shield launching and receiving shafts, logistic work sites The relationship between the excavation of running tunnel by TBM and the construction of the stations Conclusions The primary responses to the initial risks: a "city machine" and its essential characteristics Principles for making the macro choices The common solution: a "city machine" Essential components of a "city machine" Slurry and earth pressure balance shields: functioning principles and review of the state of the art Some considerations for the choice between HS and EPBS Tunnel design Prediction and control of tunnelling-induced settlements and assessment of their impacts The design of face-support pressure The design of precast concrete segmental lining Backfilling of the tail void The control of tunnel construction Updating and implementation of PAT Excavation control: the case of slurry/hydro shield (SS/HS) Excavation control: the case of earth pressure balance shield (EPBS) Integrated real-time monitoring system Health and safety General considerations TBM working environment Critical processes Additional critical elements Emergencies Case histories EOLE project - Paris St. Petersburg metro Porto light metro Turin metro line 1 SMART solution of Kuala Lumpur (Malaysia) High speed railway line of Nodo di Bologna References Appendices Appendix 1 Type and characteristics of TBMs Appendix 2 TBM manufacturers from the new millennium Appendix 3 Geotechnical investigations for tunnelling in urban areas Appendix 4 Description of the principal elements of the 12 analytical methods for defining face-support pressure Appendix 5 An example of risk management plan for a job using slurry shield Appendix 6 Typical excavation procedures for EPB shield Appendix 7 The Italian experiences Annex Contract and construction aspects Glossary of terms Index
