Shear strength

Results of triaxial tests performed in saturated and unsaturated compacted soil specimens with different interstitial fluids are presented. Tests were carried out in order to study the influence of the fluid relative dielectric constant, εr...

Several analytical methodologies help estimate the shear strength of rock discontinuities whose main limitations are the difficulty to obtain all necessary parameters to satisfactorily represent the boundary conditions and influence of infill materials. The objective of this study is to present a predictive model of peak shear strength for soft rock dis...

This paper focuses on the study of the mechanical behavior of sandy limestone rocks. These rocks are provided from the historical caves of El Haouaria, which are located on of the North Eastern seacoast of Tunisia, and were created during the Punic era. Nowadays, these caves suffer from cracks, randomly distributed with a variable opening size. While, i...

As a result of a number of studies, some analytical models have been developed to predict the shear behavior of unfilled rock joints, but they all present a purely deterministic nature because their input variables are defined without considering the uncertainties inherent in the formation processes of the rock masses and related discontinuities. This work aims ...
