Abstract: The present study shows that the cylindrical expansion tests can not only solve foundation problems by empirical method but are also a means to study the undrained behavior of cohesive soils. On theoretical grounds, it has been shown that the undrained stress-strain curve of the soil can be derived from the pressure meter curve. New testing techniques have been developed, much more sophisticated than the classical ones. The following information has been obtained on a few cohesive soils: horizontal at rest pressure; undrained stress-strain curve of the undisturbed soil for strains up to 5% and in situ undrained cohesion, which appears higher than those determined by classical methods.
