Dynamic Cone Penetrometer (DCP) Relative Density Correlations for Sands

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...

Percussive Dynamic Cone Penetrometer for Geotechnical Surface Assessment with a Planetary

Introduction: During the past planetary surface missions, few instruments have been deployed to directly assess soil physical properties like density, soil strength (internal friction and cohesion), and pressure/sinkage curves, or their spatial variation. Several Soviet lunar missions were equipped with small cone vane penetrometers, and the Apollo astronauts also used two different manual pene...

Estimating of geotechnical properties of clay soil with dynamic cone penetration (DCP) test

Dynamic cone penetration (DCP) test is used more in pavement design and construction, and less for subsurface geotechnical investigation and clay core dam. In the present article, evaluating geotechnical parameters of Sanandaj’s clay in the western region of Iran using the DCP test was taken into account. Accordingly, 6 trial pits with maximum depths of 15 m were excavated manually in various s...

Fiber Optic/Cone Penetrometer System for Subsurface Heavy Metals Detection

Robotic Lunar Geotechnical Tool

Rover-mounted geotechnical systems are of paramount importance to lunar trafficability assessment, construction, and excavation/mining toward establishing permanent human presence on the Moon. These tools can also be used to determine density, when the regolith is used as radiation shield, for example. Two popular insitu devices for establishing geotechnical properties of soil are the Static Co...
