Geothermal Energy: to heat and cool buildings

There is a form of geothermal energy which makes use of the ground at normal temperatures within a few tens of metres of the surface as a heat source in winter and a heat sink in summer to economically, efficiently and sustainably heat and cool buildings. These systems go by a variety of names including …more

E.H. Davis Award – Combined Loading Of Offshore Foundations

Predicting the bearing capacity of a foundation under combined vertical (V), horizontal (H) and moment (M) loads is a fundamental soil mechanics problem. Traditional solutions utilise ad-hoc adjustment factors to reduce the pure vertical bearing capacity in order to account for inclination, eccentricity, foundation shape and soil strength gradients. These procedures have their roots in …more

Cone Penetration Tests in Unsaturated Soils

This seminar will present results of UNSW’s ten year study on the cone penetration test in unsaturated soils. Firstly, laboratory-controlled cone penetration test results in two unsaturated soils will be presented, obtained using a suction-controlled calibration chamber. For unsaturated Sydney sand, the cone penetration resistances are found to increase significantly due to the presence of …more

Tree Roots and the Slope Stability of River Banks in Eastern Australia

Riverside vegetation is a significant factor influencing the occurrence and progress of streambed and riverbank erosion. Recent riparian management practice in Australia has focused on re-establishing or maintaining native riparian vegetation in order to control or prevent erosion as well as regenerate or preserve the complex variety of in-stream and riverside habitats. An integrated review …more

Problematic Soils

The presentation will provide a brief summary of the activities of AGS over the last 2 years and then present a technical presentation on the topic “What is the Problem with Problematic Soils?” A large number of soils are considered to be problematic (eg. Collapsible soils, Expansive soils, Peat, Silty soils, Liquefiable soils). The talk …more

Rankine Lecture: Performance Based Design In Geotechnical Engineering

Engineering design consists of a sequence of decisions which should satisfy the client’s objective performance requirements. This lecture will argue that an assessment of geotechnical performance must involve ground displacements, and that the traditional approach of specifying safety factors is potentially wasteful. In particular, the Limit State Design (LSD) approach adopted in the Eurocodes will …more

AS2870 – 2011, Residential Slabs and Footings

What should the geotechnical profession know about the changes in the Code? The Code gives references to parties their functions and responsibilities to using the code. An example is the Classifier and Qualified Engineer. Reference is made to role of Engineering Geologists and Geotechnical Engineers. To understand the responsibilities of the qualified engineers using the …more

Quality Assurance of ground improvement using down-hole video techniques

Verification of ground improvement is a topic of on-going debate. The tried and tested methods are limited in certain conditions and the geotechnical fraternity is always exploring new avenues for verification. The use of down-hole cameras has become far more readily available as the technology advances and the camera size decreases. This presentation highlights the …more

The Mystery of Unsaturated Soils

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

Introduction to the engineering geology of Hobart

The Tasmanian Chapter of the Australian Geomechanics Society is hosting an introduction to the engineering geology of Hobart. The format will be a field trip to sites of engineering geological interest between Lower Sandy Bay and Taroona. We will view many of the main geological strata present around Hobart including Permian, Triassic, Jurassic, Tertiary and …more

Rock Slope Design in Layered Rocks: Some Precautionary Tales

The coal mining industry requires slope designs in layered coal measures and other rocks on a routine basis. The scale of these slopes far exceeds that of slopes in comparable materials for civil purposes, yet the effort involved in design of mine slopes is comparatively minor. There are many reasons for these apparent discrepancies but …more
