Aims:

To instil an appreciation of the design process and design considerations, soil-structure interaction, lining design and effects on existing underground structures. To design underground structures using a rational approach and according to the CDM regulations.

Learning Outcomes: At completion, students will be able to:

  • Understand the principles of sustainability as a framework for making design decisions.
  • Understand the principles of soil-structure interaction and modes of deformation of tunnels and shafts through the use of empirical methods, simple calculations, analytical methods and numerical methods.
  • Know the sources of actions and limit states.
  • Evaluate ground conditions, assess risks, and design support requirements taking account of structural capacity, durability, water ingress/egress and fire using the Eurocodes.
  • Be able to design using materials including fibre reinforced concrete, plain or bar reinforced concrete, structural steelwork and timber.
  • Understand the limitations of empirical, analytical and numerical methods and be able to develop and implement a design strategy to solve a tunnelling problem.
