Probabilities of Failure and Factors of Safety in Geotechnical Engineering

There has been a rapid growth of interest in both academe and industry in the use of probabilistic methods in geotechnical engineering. In hindsight this is not too surprising, since soils and rocks are among the most variable of all engineering materials, and geotechnical engineers must often make do with materials they are dealt with …more

Short course: Finite Elements in Geotechnical Engineering

The short course will provide attendees with an insight into the use of finite elements in geotechnical engineering covering a range of traditional geotechnical applications: An introduction to the course materials and software Introduction to the finite element method Settlement and seepage analysis by finite elements Choice of soil properties for finite element analysis Slope …more

Laboratory testing and hydromechanical behaviour of unsaturated soils

The presentation focuses on the hydro-mechanical behavior of unsaturated soils. It is a challenging area of research, from both experimental and theoretical point of view. The role of unsaturated soils is of paramount importance in the design of engineered barriers, in the collapsible and expansive behavior of fills and natural soils, in the driving mechanism …more

Coastal Change Monitoring using Geomatic Techniques

In recent years change monitoring has become an increasingly important issue, particularly for landforms and areas that are potentially hazardous to human life and assets. The coastal zone is currently a sensitive policy area for those involved with its management, as phenomena such as erosion and landslides affect the stability of both the natural and …more

Darwin to Alice… By Rail

The Alice Springs to Darwin rail link project has been 100 years in gestation and only became reality as a result of co-operation between Federal and State Governments and the investment of private enterprise. Tendering started in 1997 with preferred construction and management team the Asia Pacific Transport Corporation nominated out of short list of …more

2003 Darcy Lecture: Ground and surface water contributions to chemical mass discharge

Richelle presented the 2003 Darcy lecture, which included the results of investigation and modelling of the migration of agricultural chemicals to groundwater. The pathways by which agricultural chemicals (nonpoint pollutants) move from fields to streams vary in time, exemplified by work from the semi-arid Palouse River watershed in eastern Washington. Precipitation is strongly seasonal, occurring …more

Geotechnical Engineering in Antarctica

At least three Australian Geotechnical Engineers have visited Antarctica in the past eight years to conduct geotechnical investigations. Most recently, Sam was contracted by the Australian Antarctic Division to visit Davis Station for a period of five months over the 2002/2003 summer. The specific geotechnical issues associated with development in the cold regions of the …more

Two presentations

Properties of a model for the yield and flow of granular materials Dr David Harris, Department of Mathematics, UMIST, UK Some properties of a continuum model for yield and flow of granular materials are presented in which a physical quantity analogous to grain rotation is incorporated by using a reduced Cosserat model. The intrinsic spin …more

Tensile & compressive capacities of piles in sand under repeated loading

A series of pile load tests were carried out in a geotechnical test pit and in a geotechnical centrifuge to determine the shaft resistance in compression and in tension during repeated loading. In the geotechnical test pit open ended steel pipe piles were jacked into compacted moist sand and after eliminating the end bearing by …more
