This module will provide advanced theory for the design of foundations to resist seismic events and deploy advanced geotechnical analysis for slope stability, assessment of tunnel and mine void stability and design of instrumentation to assess compliance of project work during construction.
Although the module has no formal pre-requisites, students must have prior knowledge of soil mechanics, geology, numerical analysis and foundation construction.
Seismic impact on foundation design
- tectonic activity and impact of world earthquake codes
- foundations designed to seismic code standards
- vibro-compaction, vibro-replacement, dynamic compaction, surcharging, pre-loading, vibro-concrete columns, lime/cement stabilisation
- numerical assessment of efficiency of ground improvement
- sustainability of ground improvement techniques and protection of controlled waters
Tunnels and subsurface voids
- numerical analysis of stress and strain concentrations around circular and elliptical subsurface voids
- numerical analysis and codes of practice governing impact of subsurface voids on stability and surface distortion
- rigorous analysis: Bishop,
- non-circular: Janbu
- parametric studies: computer software
- complex situations: wedge analysis
- impact of climate change on slope stability
- remedial measures
- water pressure: piezometer design, installation
- earth pressure: strain gauge, flat jack
- deflection: inclinometers, accelerometer, extensometer
- types of instrumentation used in surface and sub-surface monitoring
- technical limitations
Learning sessions will include lectures, seminars, tutorials and computer analysis.
Use will be made of case studies and audio-visual resources.
One assignment mark based on laboratory work, numerical analysis and design skills.
One 3 hour examination assesses numerical and design skills.
Indicative Learning Hours:
- Lectures/tutorials 11 x 3 hrs = 33 hours
- Computer analysis / simulation 6 hours
- Private study and coursework 108 hours
- Examination 3 hours
TOTAL 150 hours
when you have successfully completed this module you will:
to demonstrate that you have achieved the learning outcome you will:
|1.||Have a detailed understanding of global tectonic activity, monitoring and design codes as they impact upon and modify foundation design.||Critically evaluate and apply design principles to solve practical foundation problems in seismically active zones.|
|2.||Apply numerical analysis to seismic foundation design.||Deploy appropriate numerical techniques to apply design principles.|
|3.||Employ numerical modelling techniques to interpret stresses, strains and deformation / distortion in subsurface voids.||Select appropriate numerical technique, prepare design solutions and estimate stresses, strains and settlements to appropriate accuracy.|
|4.||Adopt appropriate ground improvement techniques and interpret the interaction between soil and structure at strategic geometric interfaces.||Select appropriate ground improvement technique and determine by analysis the soil-structure interaction between ground improvement elements and the soil being improved.|
|5.||Assess the scope of work necessary for the installation of suitable geotechnical instrumentation and use of controlled monitoring to inform the design process and so provide practical solutions to complex geotechnical problems.||Specify an appropriate monitoring programme and critically evaluate the optimum for efficiency and accuracy.|
Your achievement of the learning outcomes for this module will be tested as follows:
|Description||Design submission for a major civil engineering project encompassing soft ground and foundations in a seismically active area.||3hr end examination|
