Earthquake engineering is a broad field, drawing on aspects of geology, risk analysis and other technical areas. All such fields fall within the core services of Tonkin & Taylor. The particular area of emphasis, however, is in geotechnical earthquake engineering which includes the following:
Seismic Hazard Assessment
Local Site Effects
Design Ground Motions
Design Spectra and Response Spectra
Liquefaction
Seismic Slope Stability
Seismic Design of Retaining Walls
Seismic Design of Dams
Soil Improvement for Mitigation of Seismic Hazards
Seismic Risk Analysis.
The sources of earthquakes require knowledge of tectonics and structural geology provided by our experienced engineering geologists. The effects of earthquakes require analysis and design solutions from the specialist geotechnical engineers.
Typical tasks carried out for major projects involve the following:
Identification of active faults
Assessment of level of ground shaking
Assessment of ground rupture hazard
Site investigation and classification of site subsoil category
Evaluation of amplification of ground movements due to specific site conditions
Assessment of potential for liquefaction of ground
Evaluation of landslip risk and displacement under earthquakes.
T&T has provided Earthquake Engineering services to the following market sectors (amongst others):
Water Supply: Design and evaluation of dams
Roading: Stability of embankments, cut slopes and bridge abutments
Hospitals: Design criteria, liquefaction assessments, and local site effects
