The Odyssey Project
Project Odyssey compares the geophysical properties of soils, obtained in a high-yield non-destructive manner, with their geotechnical properties, obtained through destructive spot testing. The aim is to use geophysics to keep the number of geotechnical measurements required to a minimum, in order to determine the load-bearing capacity of different soils when landing large aircraft.
The American delegation was made up of military personnel from the Air Force Research Laboratory. They were met by the CER and ENDSUM research team managers, who introduced them to Cerema, its heavy machinery, and the work it is carrying out as part of the Odyssey project.
Designing a life-size experimental structure
As part of the project, Cerema proposed creating an experimental control structure which, combined with geotechnical tools, could be used to study the load-bearing capacity of natural soils when landing large aircraft. Another aim was to assess the extent to which geophysical methods could be used to reduce the need for this kind of testing.
Experimental surfaces 33m long and 5m wide are currently under construction at the CER facility. The surface will be composed of three layers of loam, following the process described below:
-
Clearing of the test area and compaction of the embankment surface
-
Construction of the first layer of loam
-
Series of tests
-
Repeat for layers 2 and 3
-
Additional series of tests
Geophysical readings (mainly electromagnetic) were taken in parallel during the construction phases.
