Overview

Slope design relies on both scientific theory and practical experience, with guidelines linking geomechanics research to best practices. However, in large or complex sites, slopes often interact with diverse geographic, geological and man-made features, forming interconnected systems. These complex systems evolve gradually, with subtle indicators that may precede significant failures. 

This event explores the challenges of designing and managing slopes in such environments, focusing on the interactions between slopes and surrounding infrastructure. 

Drawing on 50 years of experience, it provides insights into identifying warning signs and implementing strategies that address complex, interconnected systems to prevent adverse outcomes.

Learning outcomes

In this presentation, you will:

• understand and recognise the concept of complex systems in slope engineering, including interactions between slopes and surrounding infrastructure
• recognise how complex systems evolve gradually, with subtle signs, and assess how interactions between slope and surrounding infrastructure can lead to unexpected large-scale failures
• apply holistic design, management, and monitoring strategies that go beyond isolated slope stability to address complex, interconnected environments.

Tim Sullivan FIEAust CPEng NER

Director, PSM

Biography

Mr Sullivan graduated from Macquarie University in 1973 with a degree majoring in geology. He joined Coffey’s in 1974 and was employed with them till 1993. While at Coffey’s Tim was a Director of the firm and established the Mining Geotechnics Group. In 1979-80 he undertook postgraduate studies in London and was awarded an MSc from the University of London and a DIC from the Imperial College of Science and Technology. 

From 1992-1993, he was a Visiting Professor at the School of Mines, UNSW, from 2002 to 2007 Adjunct Professor of Geotechnical Engineering, UNSW and from 1997 to 2000 he was also the NSW Coroner’s adviser on the Thredbo Landslide. In 1993 Tim established his own firm Pells Sullivan Meynink (PSM). 

Tim has been a geotechnical consultant for some of the world’s largest mining operations and companies including BHP Billiton, Rio Tinto, Xstrata, Glencore, Newmont, Anglo Gold, Pilbara Iron and Newcrest. In addition to all the states and mainland territories of Australia, major projects have been located in India, Papua New Guinea, Indonesia, Thailand, Laos, Africa, South America, Chile, Philippines, Mexico, New Zealand and Fiji. Tim has worked on more than 400 mining projects at all stages from planning to operating.
