Leader: Professor K. Soga / Dr. C. Burgoyne
Timing: Weeks 1-4 Easter term
Structure: 14 lectures + 2 examples classes, 4 lectures/week
The aims of this course are to:
- Act as a shop window for
the techniques and technologies of civil engineering seen as a practical
and scientific discipline.
- Create interest in the
design and construction of underground facilities, with illustrations from
recent schemes, and in so doing highlight the role of the professional.
- Introduce the materials of
underground construction: soil, and reinforced concrete.
- Introduce the principles of
soil mechanics, and to demonstrate their application to the design of
Students who have taken the course should be able to:
- Select a method of
underground construction which will be appropriate to some specified set
of ground conditions.
- Relate soil voids ratio to
its bulk density, and calculate vertical stresses.
- Interpret tests to
determine the strength of soils, so as to obtain appropriate
"undrained" (single-phase) or "drained" (dual-phase)
- Use Mohr circles of stress
to calculate the possible bounds to the lateral earth pressure:
"active" (minimal) and "passive" (maximal).
- Use active and passive
pressures to dimension satisfactory earth retaining walls, and calculate
shear forces and bending moments.
- Calculate the design
flexural strength of reinforced concrete sections, using appropriate
- Outline the internal
stress-distribution in reinforced concrete walls, and make proposals for
- Discuss the detailing of
reinforced concrete retaining walls constructed in various ways.
- Discuss the factors influencing
design and construction of bored tunnels in urban areas.
- Illustrate the handling of
uncertainty and risk in construction underground.
