A microelectromechanical system digital 3C array seismic cone penetrometer

Near-surface VSP surveys using the seismic cone penetrometer

We have found that high-quality vertical seismic profile (VSP) data can be collected for near-surface applications using the seismic cone penetrometer. Conemounted accelerometers are used as the VSP receivers, and a sledgehammer against the cone truck baseplate is used as a source. This technique eliminates the need to drill a borehole, thereby reducing the cost of the survey, and results in a ...

Fiber Optic/Cone Penetrometer System for Subsurface Heavy Metals Detection

design, fabrication and evaluation of a tractor mounted digital cone penetrometer

for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...

A Dynamic Cone Penetrometer for Measuring Soil Penetration Resistance

ters to characterize both agricultural and rangeland A DYNAMIC CONE PENETROMETER soils, however, has been limited by concerns about (i) FOR MEASURING SOIL instrument cost, (ii) measurement repeatability, (iii) limited ranges of soil resistance that can be measured by PENETRATION RESISTANCE a single penetrometer, and (iv) difficulties in comparing Jeffrey E. Herrick* and Tim L. Jones data collec...

Design, Construction and Evaluation of a Digital Hand-pushed Penetrometer

A cone penetrometer is widely used in tillage and off-road mobility research as an indicator of soil strength and density characteristics. Light-weight, manually operated units are especially useful in recording cone index determination at remote field locations. An electronically hand-pushed soil penetrometer with a microcontroller-based data logging system was designed and fabricated to provi...
