VARIATIONS IN PRESSUREMETER MODULUS (EM)

Abstract

The modulus EM is frequently used in the design of foundations to estimate the displacement of
geotechnical structures, for loaded foundations, flexible earth retaining structures, and even as a first assessment for
embankment lying on compressible soil. One of the main parameters that interpreted from Menard Pressuremeter
test is the elastic modulus. Different methods been used to explore the values of EM from pressuremeter tests, in the
present paper three methods utilized to interpret the pressuremeter tests modulus that conducted in a site in Abu
Dhabi. The methods showed great discrepancies in the deduced values of the elastic modulus for the same tests. The
differences in the results may reach to 80%, the present study also suggested a reliable method of analysis for the
pressuremeter modulus.
