Abstract The paper presents a numerical analysis of pressuremeter test in unsaturated cohesive soils. In practice, is commonly expanded up to 10–15% cavity strains. At these strains, limit pressure not usually reached, and its value estimated by extrapolation. Accordingly, authors suggest using at 10% strain ( P 10 ) for the interpretation rather than pressure. this strain, it also assured that...

Soil deformation modulus is an essential parameter for the analysis of behavior of substructures. Despite its importance, little attention is paid to developing empirical models for predicting the deformation moduli obtained from the field tests. To cope with this issue, this paper presents the development of a new prediction model for the pressuremeter soil deformation modulus utilizing a line...

A study is made of the problem of interpreting the results of Menard pressuremeter tests on soil in situ. In the test a cylindrical cavity is expanded by internal pressure, and the relation between applied pressure and cavity vulume change is measured. It is shown that the results of a single test are enough to determine a complete stress-strain relation in plane strain, and a simple graphical ...

This paper presents an experimental study aimed at evaluating the measuring capabilities of innovative monocellular pressuremeter probe, Monocell Francis Cour based on calibration testing in laboratory. The originality tested equipment is to allow evaluation soil properties both small- and large-strain domains, without need sophisticated point displacement arms. focuses small-strain shear modul...
