Geotechnical

Civil and Construction Engineering
Faculty Research Area

The mission of the Geotechnical Engineering group is to develop and advance new knowledge in geotechnical research and practice, with a focus on promoting resilient and sustainable civil infrastructure systems across coastal, transportation, natural and built environments. Our research focuses on fundamental static, cyclic, and dynamic soil behaviors, and on full-scale field studies, using laboratory and in-situ testing and characterization, physical modeling, in-situ and remote monitoring, and computational modeling and simulation. 

Faculty work closely with state and federal partners, industry, and university partners to turn discoveries into real-world applications through the development of new materials, construction methods, monitoring techniques, performance-based design methodologies, and reliability, hazard and risk assessments. Our projects use state-of-the-art facilities at Oregon State and field sites across Oregon and the Pacific Northwest, backed by novel sensing and data collection, geospatial tools, and advanced numerical simulation. Our sponsors include the National Science Foundation, the U.S. Army Corps of Engineers, the Oregon Department of Transportation, FHWA, NCHRP, the U.S. Department of Agriculture, the M.J. Murdock Charitable Trust, and industry partners. 

Key Focus Areas

  • 3D printing with soil-binder mixtures
  • Biogeotechnics and bio- and low-carbon binders
  • Coastal geotechnics
  • Earthquake engineering
  • Full-scale and in-situ testing under static and dynamic loading
  • Ground improvement for static, seismic, and vehicular loading
  • Landslide initiation, monitoring, and slope stabilization
  • Micromechanical experimentation and discrete element modeling
  • Multi-hazard/cascading hazard analyses and evaluation
  • Soil-structure-interaction: shallow and deep foundations, earth retaining structures
  • Static, cyclic, and dynamic soil behaviors, challenging soils

Geotechnical Materials & Soils Mechanics Laboratory

The lab is equipped to conduct numerous index tests on materials as well as suction measurement and control, permeability and consolidation, thermal testing, direct shear, triaxial, and specimen fabrication for novel binders and 3D printed earthen systems.

O.H. Hinsdale Wave Research Laboratory

Featuring a Large Wave Flume and Directional Wave Basin, the lab enables controlled studies of coastal and overland wave loading, scour/erosion, sediment transport, and soil–foundation–structure interaction under extreme events.

Geotechnical Engineering Field Research Site (GEFRS)

The site provides researchers, engineering practitioners, and contractors with a well-characterized site for state-of-the-art research and full-scale product testing.
