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

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

El Viar Dams In Southern Spain:
Embracing Expansive Clay

Dam Construction Using Expansive Clay,<br>Case Study of two dams built in Southern Spain in 2007-2008 Abstract The use of expansive clay in road construction and dry embankments is well established thanks to traditional soil stabilisation methods. However there is relatively little experience in the use of expansive clay for the construction of large earth dams …more

Risk Management for Onkaparinga Coastal Cliffs

Abstract Onkaparinga Council is responsible for managing approximately 30 km of coastline, comprising a wide variety of coastal land forms and geologies including spectacular cliffs and stunning beaches. However, along with its outstanding natural beauty, this coastal strip is also subject to significant and ongoing erosion and slope instability as a result of the dynamic …more

SA-NT AGM, followed by the 55th Rankine Lecture:
Hazard, Risk and Reliability in Geotechnical Practice

The lecture will immediately follow after the SA-NT Chapter Annual General Meeting. “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 …more

Micro-seismic monitoring of damage initiation and propagation in an underground gallery in the Opalinus Clay formation (Switzerland)

Abstract We report the results of the analysis of the micro-seismicity induced by an excavation operation in the Opalinus Clay formation in Switzerland. This formation is considered for the potential storage of radioactive waste, and the monitoring of the micro-seismicity is used to characterize the evolution of the mechanical damage of the rock surrounding the …more
