ABSTRACT: This paper presents the results of thirteen pressuremeter tests conducted in Clearwater Formation Clayshale at Syncrude’s oil sands operations near Fort McMurray. This paper performs an interpretation of nonlinear stiffness data from undrained pressuremeter tests. The behavior of the secant shear modulus for several shear strain values is analyzed and a comparison of the nonlinear stiffness is made using London clay as a reference. In addition, the initial modulus obtained with shear wave velocity values derived from seismic tests is included. Finally, the stiffness parameters for the Clearwater clayshale are presented.
