Shear Strength of Prestressed Cohesive Soils
Journal of Geotechnical Engineering, 1987The results of an experimental investigation to determine the effects of preloading on the Mohr-Coulomb failure envelopes of cohesive soils are described. In situ shear tests using the Borehole Shear Test (BST) were performed on a number of natural soil deposits.

Estimation of runoff critical shear stress for soil erosion from soil shear strength
CATENA, 2004Critical shear stress is an important soil parameter governing detachment by runoff which appears in numerous erosion models. Soil shear strength has been often presented as the best soil property to predict critical shear stress. However, only a few studies have documented the relationship between soil shear strength and critical shear stress, and the

Chapter 6 defines shear strength and explains its different types, essential for understanding soil stability. It introduces the Mohr-Coulomb failure criterion, which describes soil strength under varying stress conditions. The chapter also discusses the state of stress at a point within a soil mass and introduces the concepts of Mohr's circle and ...

Shear strength behaviour and the measurement of shear strength in residual soils
2012The selection of appropriate strength parameters and the prediction of deformation and failure are important steps in the design of foundations and cut slopes in residual soils. In countries with widespread residual soils, strength testing practice, both in the laboratory and in the field mostly follows standard procedures, employing triaxial and shear

Recovery of Strength Along Shear Surfaces in Clay Soils
2013The residual shear strength as operative strength along the shear surface is commonly used for analyzing the stability of reactivated landslides. On this base, it is not possible to have brittle failure or progressive failure mechanisms. In fact, these kinds of phenomena claim for a recovery of strength along the shear surface, which is due to ageing ...
