Relation Between DCP Data and Geophysical Measurements on Unimproved Landing Zones
Abstract
The objective of the Odyssey project is to identify the optimal set of geophysical methods for estimating soil bearing capacity. In order to study the geophysical response to different states of soil compaction, a full-size test site has been designed using as construction material a standardized clayey silt. The test site is a backfill of the aforementioned silt with a constant water content with a size of 5 m x 29 m and a thickness of about 0.75 m including three zones with different compaction levels. The results obtained allow to identify a significant link between the measurements obtained by Dynamic Cone Penetrometer (DCP) and the measured geophysical quantities such as electrical, mechanical and electromagnetic properties. These results now have led to the determination of the appropriate protocols to adjust the relationships between geotechnical properties from DCP measurements and the main near-surface geophysical investigation methods. They are therefore a very interesting source of information for on-the-fly mapping of bearing capacity properties from geophysical measurements in complex geological contexts where the proportion of clay in the soil is significant.
