Discussion: Cone penetrometer and liquid limit

a comparison of liquid limit value determined using the casagrande and cone penetrometer

depending on the moisture contents, the soil behavior is revealed as solid, semisolid, plastic and liquid states. liquid limit is an important property of fine-grained soils and casagrande and cone penetrometer are two different methods employed for the determination of liquid limit of the soil. in forest environment, the casagrande method is the classic method for liquid limit determination, b...

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...

Fiber Optic/Cone Penetrometer System for Subsurface Heavy Metals Detection

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 ...

Subsurface Exploration Using the Standard Penetration Test and the Cone Penetrometer Test

The Standard Penetration Test (SPT) and Cone Penetrometer Test (CPT) have become industry standards for subsurface geotechnical investigations using small diameter (<8-in. [20-cm]) borings and soundings. Both procedures have evolved over a period of 100 and 70 years, respectively, and have been adopted as ASTM standards. Each procedure has certain advantages over the other, but both can elicit ...
