Derivation and discussion of the Ordinary Method of Slices with attention to pore pressures, effective stresses and practical limitations.

This paper reports the limitation of the conventional Bishop’s simplified method to calculate the safety factor of slopes stabilized with anchors, and proposes a new approach to considering the reinforcing effect of anchors on the safety factor. The reinforcing effect…

2D slope stability analyses have been performed using various software packages on a routine basis in geotechnical engineering since the 1980s. Many of these 2D packages are now used by geotechnical consultants, often with little regard for the potential differences…

Pre-stressed anchor cables are widely used in slope engineering for effectively improving slope stability as a reinforcement measure. Based on assumptions of stresses on a slip surface, this work proposes a new limit equilibrium (LE) method to analyse the stability…

Analysis of slopes stability for weathered crystalline rocks like the schists of Caracas necessitates an approach distinct from procedures routinely applicable to hard, fractured rocks, on the one hand, or soils, on the other hand. Neither of the latter two…

Instabilities in rock slopes are often triggered along planar joints with weakened shear strength, inducing translational failures. In intact rocks, however, the kinematics of failure may exhibit rotation, which is a more common occurrence also in soil slopes. A slope instability in…

Slope failures in opencast coal mines in the Northern Waikato Coal Region commonly occur in the vicinity of major faults where they define pit limits.  In-pit engineering geological mapping at the Kopuku Sector of the Maramarua Coalfield demonstrates the existence…

Landslides pose significant risk to the communities and infrastructure, particularly in mountainous regions. Accurate estimation of landslide slip surface depth/geometry and volume of displaced material is crucial for hazard assessment, borehole planning and mitigation strategy. This study presents a novel,…

Mount Maunganui is a rhyolite dome that stands 232 metres above sea level at the entrance of the Tauranga Harbour. In January 2011, Cyclone Wilma triggered several tens of landslides at this site. This study reviews the spatial distribution of…

Study of several field case histories has shown that the difference between two- and three-dimensional factors of safety is most pronounced in cases that involve a translational failure. Two- and three-dimensional slope stability analyses of field case histories and a…
