Ruth Allington is an engineering geologist by training. She is Joint Senior Partner of GWP Consultants LLP, the firm she joined in 1981 immediately after graduating (then the Geoffrey Walton Practice). In addition to her BSc and MSc degrees, she also has an MBA, and she is a qualified…
Abstract The movement of many landslides is controlled by the force imbalance associated with a reduction in shear resistance caused by a decrease in normal effective stress as pore water pressures increase. This basic premise might lead to an assumption that the movement rate has…
Abstract Routine effective stress analyses for failure of geotechnical structures use a linear Mohr-Coulomb envelope and routine analyses for ground movements use linear elasticity with constant Young’s Modulus E’ or one-dimensional modulus M’. Observations of soil behaviour show that strength and stiffness are non-linear and…
More and more, society requires to know the risk which people, property and the environment are exposed to. The role of the geotechnical engineering profession should increasingly be reducing exposure to threats, reducing risk and protecting people. The objective of the 55th Rankine Lecture is…
Presented by Professor John Atkinson Senior Principal, Coffey Geotechnics Emeritus Professor of Soil Mechanics, City University London on 28 November 2017 at Auckland University. The talk describes how to investigate and model the ground, how to determine parameters and how to perform simple analyses. A…
Presentation by Dave Petley. Dave is the Pro-Vice-Chancellor (Research and Innovation) at the University of Sheffield in the United Kingdom. His blog provides a commentary on landslide events occurring worldwide, including the landslides themselves, latest research, and conferences and meetings.

Pseudostatic slope stability procedures can be employed in a straightforward manner, and thus, their use in engineering practice is appealing. The magnitude of the seismic coefficient that is applied to the potential sliding mass to represent the destabilizing effect of the earthquake shaking is a…
Engineering geology has a long and rich heritage and the United Kingdom has been in the vanguard of the development of the subject as a distinct discipline with the first book on the subject being published in London in 1880. Since then engineering geology has been applied to projects…
