Bogong Power Development Project Geotechnics

The completion of the Bogong Power Development Project during 2009 in the alpine region of north east Victoria involved construction of 7.6 km of tunnels and shafts and an underground power station. The project cost was $240 M and provided 140 MW of power. This project saw the completion of the ‘missing link’ in the More Information…

“Geomechanics and Engineering” Australian Lecture Tour May 2012

Through the efforts of the Engineers Australia SA Division Footings Group and Dr Don Cameron, we present a lecture series by Professor Robert Lytton. This tour has been organised by the Housing Engineering, Design & Research Association (HEDRA) in conjunction with the SA, Queensland, Newscastle, Sydney and Melbourne chapters of the Australian Geomechanics Society (AGS), More Information…

Advances in Geotechnics of Roads and Railways

Introduction The Sydney Chapter of the Australian Geomechanics Society (AGS) is proud to present its sixteenth annual Symposium to be held on 10 October 2012, titled “Advances in Geotechnics of Roads and Railways”. The Symposium forms part of the continuing program of events by the Sydney Chapter of the AGS, designed to keep the engineering More Information…

Some Mining Application of Unsaturated Soil Mechanics

Unsaturated soil mechanics continues to play poor relation to saturated soil mechanics, in part because of the dominance of conventional soil mechanics approaches involving saturated conditions, perhaps because the inclusion of another phase (air) adds considerable complexity, and because a soil at a given density is stronger, less compressible and less permeable (i.e. performs better) More Information…

The NSW Research Award

Experimental investigations into using non-destructive techniques for Characterising compacted soil Ana Paula Heitor, University of Wollongong Conventional field compaction control methods, including nuclear gauge, sand cone and rubber balloon, perform well for controlling the compacted soil at time of placement; however because of their localised nature these techniques may not be suitable for deeper fills More Information…

Grouting at Ipswich and Hunter Expressway

Abstract – Part 1 – Ipswich Motorway, Bill Holz The upgrade of one of Queensland’s busiest road transport corridors, the Ipswich Motorway, between Dinmore and Goodna by the Queensland Department of Transport and Main Roads (DTMR) involved re-aligning the motorway corridor over two separate abandoned coal mines and adjacent a third. During the preliminary site More Information…

Working platform assessments for tracked plant

Every year piling rigs fall over or are subject to near misses due to inadequately prepared or maintained site surfaces – often such incidents involve potential fatalities or serious injury to operatives and extensive damage to equipment. Modern piling equipment is becoming increasingly heavy, often with higher centres of gravity, to cater for the demand More Information…

Design of Columnar-Reinforced Foundations

The design of columnar-reinforced foundation usually involves two verifications, first, the bearing capacity and, second, the settlement that can be completed by the acceleration of consolidation settlement. The basis of suggested methodology consists in estimating, first, a minimum improvement area ratio (IAR) complying with the allowable bearing capacity of reinforced soil; then a maximum IAR More Information…

Geology and Geomorphology of Bacchus Marsh Region: Field Trip

The geology and geomorphology of the Bacchus Marsh region has been of interest to geologists since the 1860’s, with a wide range of rock types of various ages and depositional environments present. The extraction of natural resources has been an important industry in the area, with brown coal, basalt, sands and gravels worked from the More Information…

Some Lessons From Geotechnical Failures

Dr David Tonks will discuss a number of recent significant geotechnical ‘failures’, many of which have resulted in substantial damage and cost. Some have ended up in complex and expensive litigation. Examples include construction on very soft ground, with some ongoing consolidation settlements exceeding 2 m, collapse of an arch tunnel structure during construction, movements More Information…
