Seismic and Earthquake Engineering


GDI provides evaluations of seismic and earthquake hazards, provides experienced evaluations of damage, and offers cost-effective solutions to problems. GDI professionals have authored or co-authored technical papers or research reports related to seismic and geotechnical earthquake engineering.

GDI has the experience and capability to perform fault investigations, site and subsurface characterization of dynamic soil properties, laboratory testing, and engineering analysis necessary to evaluate the potential for earthquake hazards such as:

  • Fault Rupture Studies
  • Ground Shaking Potential
  • Site (Soil) Response
  • Soil-Structure Interaction
  • Foundation Response
  • Liquefaction
  • Bearing Failure
  • Lateral Spreading
  • Retaining Wall Stability
  • Earthquake-Induced Settlement
  • Landslides
  • Slope Deformation
  • Dam And Dike Stability
GDI maintains a suite of computer analysis tools, including proprietary research, and commercial computer software, that can be used to evaluate the potential for seismic hazards, analyze potential effects of seismic hazards and evaluate cost-effective mitigation alternatives.

GDI professionals are experienced in providing recommendations and project specifications for soil improvement and other measures to mitigate seismic and earthquake hazards.  Our experience includes evaluations for stone columns, dewatering, over-excavation, in situ soil mixing, grouting, soldier pile construction and deep dynamic compaction.
