Rankine Lecture – Geotechnical Stability Analysis

Presentation details 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. This …more

Soil and Rock Logging – AS 1726 Geotechnical Site Investigations

The course aims to educate geotechnical/environmental engineers, geologists and geotechnicians who find themselves logging and/or interpreting soil and rock logs in accordance with AS 1726 – Geotechnical Site Investigations. The content assumed that the participants already have a basic understanding of soil and rock logging. The course is particularly relevant to professionals starting their careers, …more

The Lessons From The Yallourn Enquiry

Presentation details 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, …more

Evaluation of the Stability of an Arch Dam Founded on Fractured Rock

Antonio outlined a case study involving three dimensional finite element analysis of a 150m high arch dam founded on fractured Cretaceous limestone. Key constraints were limited abutment resistance and unfavourable defect orientation. Details of data acquisition including in situ rock mass shear testing were presented. The finite element analysis modelled discontinuities using individual joint elements …more
