55th Rankine Lecture:
Hazard, Risk and Reliability in Geotechnical Practice (postponed to 12 DEC)

“Doubt is an uncomfortable condition, but certainty is a ridiculous one” – Voltaire Abstract 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 …more

Deconstructing Engineering Geological Models

Abstract The use of engineering geological models to manage risks and facilitate project success is becoming increasingly common, but the rules for creating effective models are as yet unclear.  Projects are now challenged by factors ranging from climate change to political uncertainty and so there is an increasing need to elucidate those rules – so …more

51st Rankine Lecture – Geotechnical Stability Analysis – 2016 Newcastle

About the presentation Historically, geotechnical stability analysis has been performed by a variety of approximate methods that are based on the notion of limit equilibrium. Although they appeal to engineering intuition, these techniques have a number of major disadvantages, not the least of which is the need to presuppose an appropriate failure mechanism in advance. …more

Forest and bio-engineering rock fall protection techniques

Abstract A number of studies have demonstrated that forests can be an efficient and cost-effective means of protecting against rock-fall. This is especially true for events involving small blocks (< 5 m3). Incorporating the effects of forests in rock-fall propagation models is complicated by the mechanical processes that occur between blocks and trees. Although existing …more

Railway Tunnel Remediation in the Bylong Valley

Abstract In recent years rail tunnels on the Ulan Line at Kerrabee and Murrumbo in the Bylong Valley have been suffering from track geometry issues and mud pumping. Investigations have shown that the natural material beneath the tunnel’s floor slab has been pulverised by cyclic coal wagon loads, resulting in: voids, cracking and subsidence of …more

2016 Newcastle Geology Tour

About the Tour The Newcastle chapter of the AGS is pleased to announce plans for a geology tour in the Lower Hunter Valley. The 2016 excursion will follow a transect across the Lochinvar anticline, beginning with an overview of the lower Hunter Valley from the top of Mount Sugarloaf, and proceeding to follow the Hunter …more

Mechanics of Unsaturated Soils

Abstract The effective stress principle is one of most fundamental contributions in the field of soil mechanics. It converts a multi–phase, multi–stress state porous medium to a mechanically equivalent, single-phase, single-stress state continuum, thus allowing the application of the principles of continuum solid mechanics to fluid-filled deformable porous media. Without the advent of the effective …more
