Discussion: A one point cone penetrometer liquid limit test?

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...

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 ...

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...

Ising universality class for the liquid-liquid critical point of a one component fluid: a finite-size scaling test.

We present a finite-size scaling study of the liquid-liquid critical point in the Jagla model, a prototype model for liquids that present the same thermodynamic anomalies which characterize liquid water. Performing successive umbrella sampling grand canonical Monte Carlo simulations, we evaluate an accurate density of states for different system sizes and determine the size-dependent critical p...
