Analysis of Pressuremeter Testing: Evaluating Anisotropic Behaviour, Operational Stiffness, and Non-Linear Elasticity in Soils and Soft Rocks
Analysis of Pressuremeter Testing: Evaluating Anisotropic Behaviour, Operational Stiffness, and Non-Linear Elasticity in Soils and Soft Rocks
This paper presents ongoing research on pressuremeter testing at the Universities of Saskatchewan and Alberta, Canada. It discusses methods to evaluate the transverse anisotropic behaviour of soils and soft rocks, and the determination of the operational stiffness of structured formations. Additionally, it outlines a method for analyzing the unloading arm of tests in sands using hyperbolic non-linear elastic conditions, which provides a seamless transition from elastic to plastic deformations. The hyperbolic analysis also introduces a new method for estimating the small strain shear modulus from the loading branch of unload-reload cycles.
