Stability of Low Embankments on Soft Clay. Part 2. Studies of Vane and Penetrometer Tests during Centrifuge Flight.

Abstract

Correct assessment of soil parameters in centrifuge tests requires these to be measured during flight, and small vane and penetrometer devices have been developed for this purpose. The vane is fixed in position, but the penetrometer can traverse the length of the model, allowing tests to be made a different locations. A programme of tests has been conducted in the centrifuge at 100 g investigating the use of these test methods in consolidated beds of clay. Rate effects are studied for both types of tests and correlations made between cone resistance and undrained shear strength measured by the vane. A number of penetration tests were also performed to show the progressive increase in strength of a clay bed under staged embankment construction.
