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. On a etudie le probleme pose par l'interpretation des resultats fournis par le pressiometre Menard in situ. Dans ce type d'essais, une cavite cylindrique verticale est dilatee par pression interne. On mesure la relation entre la pression appliquee et le changement de volume de la cavite. On montre que les resultats obtenus avec un seul essai sont suffisants pour determiner une relation complete ‘con...
