Abstract

A method of analysis to predict the in situ maximum shear modulus Gmax,0 from self-boring pressuremeter unload tests is presented. The method considers both the stress and void ratio changes induced by pressuremeter loading and the nonlinear stress-strain response upon unloading. The results are presented in the form of a chart that allows Gmax,0 to be determined from the equivalent elastic unload modulus, G*, for a wide range of loading and unloading conditions. The analysis procedure is checked with chamber tests and field data and the results are found to be in good agreement provided factors to account for disturbance and anisotrophy are considered.

Gmax From Pressuremeter Tests: Theory; Chamber Tests; and Field Measurements

St. Louis, Missouri
