Characterization of rock and soil massifs for civil engineering projects
Knowledge about the rock and soil massifs where civil engineering works will be implemented is essential for the preparation of technically and economically coherent projects. Identifying the spatial distribution of materials in the subsoil, characterizing their properties and determining the state of stresses allows for the design of safer civil works, optimization of resources and lower environmental impacts. With this approach, IPT prepares geological and geotechnical models of natural massifs and uses three-dimensional visualization tools to aid communication with clients and underpin technical design decisions.
IPT has a multidisciplinary team of geologists, geophysicists, geotechnical engineers and physicists who prepare geological and geotechnical models, and interpret, analyze and integrate the results of different investigative methods offered to clients. The following direct and indirect techniques are employed in the field and laboratory:
- Geological and geotechnical mapping on a scale appropriate to the work
- Structural geology studies to analyze slopes and underground works and determine stresses in rock massifs
- Geotechnical and geomechanical classification of natural massifs
- Laboratory tests on soils and rocks
- Specialized field trials: CTPu, crosshole, geophysical profiling of survey drillings (OPTV, BHTV, sonic, gamma, impeller and heat flowmeter)
- Geophysical tests: seismic testing of soils (refraction, reflection, MASW) and submerged areas (continuous seismic profiling, ultra- and echo-sounding); electrical resistivity: spontaneous potential, magnetometry, GPR.
