Undrained Plane-Strain Expansion of a Cylindrical Cavity in Clay: A Simple Interpretation of the Pressuremeter Test

Abstract

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 volume 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 procedure for doing this is derived. The only restrictive assumption necessary is that the deformation is under undrained conditions; there is no restriction to infinitesimal strain or to elastic perfectly-plastic soils.
