Abstract
Rock slope analyses cannot be performed without a knowledge, or at least, a reliable estimation of the shear strength of the potential failure surface.
Some of the parameters concurrent to determination of the shear strength along joints of rocks with a rigid behaviour are considered, for the purpose of making this determination as quick and accurate as possible.
Some remarks are especially developed, based on experimental data, covering joint wall compressive strength, the uniaxial compressive strength of the rock material, the basic friction angle and joint roughness.
Résumé
Les analyses de la stabilité des versants rocheux ne peuvent pas être effectuées sans une connaissance-ou du moins une évaluation plausible de la donnée principale, la résistance au cisaillement de la surface potentielle de rupture.
On analyse certains paramètres qui concourent à la détermination de cette résistance le long de joints dans des roches à comportement rigide avec pour but de rendre cette détermination plus rapide et précise.
On prend en particulier, en considération des données expérimentales, concernant la résistance à la compression des parois des joints, la résistance à la compression uni-axiale de la roche, l'angle de frottement interne et la rugosité des joints.
