Abstract

This paper presents a conceptual testing procedure and analytical development of a free-falling full-flow penetrometer. In a free-fall penetration test, the velocity changes with depth and the soil is inherently softened throughout the testing process. Investigation of the undisturbed soil properties, thus, requires a thorough large-displacement rate-dependent analysis. This paper uses previous work's analysis for constant-rate full-flow penetration with strain-softening and rate-effect treatment, implemented in a penetrometer's equation of motion, to evaluate a continuous profile of the undisturbed undrained shear strength throughout the freefalling penetration, until a full stop. A conceptual testing procedure is presented in light of the required penetration depth, device weight and falling height, with a reference to the developed analysis and correlations.
