Shear strength
Products derived from tires have been increasingly used for geotechnical engineering applications because of the economic, environmental, and social benefits they provide. The objective of this paper is to analyze the effect of the addition of rubber fibers from unserviceable tires on the hydromechanical behavior of argillaceous soil from the Barreiras Formation...

Tropical soils have been extensively studied to evaluate the technical feasibility of their application in hydraulic earthworks such as compacted clay barriers in landfills. In these earthworks, the water flow in the porous medium generates percolation forces that can promote structural changes in the soil, with possible deleterious repercussions on its mechanic...

<p><span style="mso-ansi-language: EN-US;" lang="EN-US">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, <em>ε<sub>r</sub></em>...

<p>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...
