Relation between DCP data and geophysical measurements on unimproved landing zones

Abstract

Characterizing potential landing zones is an enduring DoD (Department of Defense) requirement. The only currently approved process involves using the Dynamic Cone Penetrometer (DCP) in order to determine the California Bearing Ratio (CBR). The DCP test is labor and time intensive and frequently done in hostile locations. A variety of geophysical techniques have been widely used for characterizing soil composition. This effort is designed to further understand whether these geophysical techniques can been applied to the characterization of potential landing zones. In order to further develop this approach, we propose to use geophysical techniques to characterize the near surface variability mainly due to structural and hydraulic properties: EMI (electromagnetic induction), ERT (electrical resistivity tomography) and MSAW (Multichannel Seismic Wave Analysis). The present project aims to state a quantitative relation between standardized compacted zones and on the go (electromagnetics based essentially) geophysical measurements.
