Numerical Analysis: A Virtual Dream or Practical Reality?

The development of numerical analysis and its application to geotechnical problems over the past 20 years have provided geotechnical engineers with an extremely powerful analysis tool. However, the use of such analysis is still not widespread, and when it is used there is all too often evidence of bad practice. Part of the reason for …more

Poulos Lecture: Tunnels and Excavations: Ground movements and the construction process

Infrastructure development invariably involves construction of excavations in the ground. These may be long and horizontal – tunnels – or short, often wide and vertical – basement excavations or cut-and-cover tunnels. The excavations need to be formed safely, so stability can be an issue, and increasingly there are major concerns about the assessment and control …more

Geotechnical Investigation of a Large Tailings Facility

The talk will present a case history of a recent geotechnical investigation for a large tailings facility in South America where liquefaction was a major design issue. The investigation involved seismic Cone Penetration Tests with pore pressure measurements (SCPTu) as well as conventional boreholes, SPT and samples. The presentation will describe the tailings deposit, site …more

50th Rankine Lecture: Stiffness at Small Strain – Research and Practice

The rapid development of computing power and numerical modelling software over the past forty years has made sophisticated analysis of geotechnical problems accessible to most practising engineers. Typically computer packages now offer a wide range of constitutive models, which the design engineer needs to choose between, and then obtain parameters for. For those structures designed …more

The Lessons From The Yallourn Inquiry

The northern batter of the Yallourn mine collapsed suddenly on the 14th November 2007. The collapse had dramatic consequences with loss of 20% of Victoria’s power generation capacity and a cost to the mine measured in hundreds of millions of dollars. Because this was a surprise to government and because of the consequences, the government …more

Rock mass characterisation: A vehicle to translate Geology into the design of Engineering Structures

The integration of site geology with engineering requirements is the basis of Engineering Geology, and there continues to be a need to describe site geology in terms appropriate for the analyses of deformation and stability of ground in situ. Two developments hold the potential to improve such description: the characterization of soil and rock, and …more
