Remote sensing of terrain trafficability

The primary goal of this investigation is the development of new and improvement of the existing methods and models of terrain trafficability prediction based on a combination of several remotely sensed modalities. These include Hyperspectral Imaging (HSI), Synthetic Aperture Radar (SAR), Thermal Infra-Red (TIR), and LiDAR (Light Detection and Ranging) techniques. Two field campaigns have …more

Geotechnical site exploration and geo-engineering education in 2013 and beyond

The best available program for geotechnical site exploration involves a blend of rotary drilling and sampling operations, laboratory testing, in‐situ field tests, and geophysical measurements, all taken within the context of engineering geology. Yet, this is only viable when sufficient funds and time are available, specifically large or critical projects. Thus, for everyday routine site …more

The award aims to provide a …more

Risks associated from coal seam gases and products of combustion gases when conducting exploration and site investigations in abandoned mine workings

Many abandoned coal mines and the adjacent fractured strata contain poisonous, noxious or flammable gases. Unmined seams also have gases. Other gases are formed from low or high temperature oxidation when oxygen is introduced into mined areas that have previously been sealed when boreholes or other penetrations intercept the workings or fractures zones. These gases …more

Sustainable Aggregates Information Seminar

The purpose of this short seminar is to present the outcomes of the Sustainable Aggregates SA development project undertaken by ARRB under a grant provided by Zero Waste SA, and equally supported by industry organisations Adelaide Resource Recovery and Resourceco. Through the development of a website the project has sought to provide industry in terms …more

Soil & Rock Logging Course – AS1726 Geotechnical Site Investigations

This one day course will aim to educate geotechnical engineers, geologists, geo‐technicians and other relevant professionals in logging and/or interpreting soil and rock logs in accordance with AS1726 – Geotechnical Site Investigations. This course is aimed at educating the profession and is particularly relevant to geotechnical and mining consultants, geotechnical contractors and laboratory geo‐technicians and …more

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

University Research Student Presentations

Research students from our Victorian institutions will give a short talk on their research projects throughout the technical meeting. The main objective is to let the AGS members know about some of the current research and development studies being undertaking in Victoria, and to share and discuss R&D needs and ideas. Topics and speakers are …more

Symposium – Retaining Structures: Recent Advances and Past Experiences

The Sydney Chapter of the Australian Geomechanics Society (AGS), in conjunction with the Engineers Australia Structural College, is proud to present their seventeenth annual Symposium to be held on 13 November 2013, titled “Retaining Structures: Recent Advances and Past Experiences”. The Symposium forms part of the continuing program of events by the Sydney Chapter of …more

2013 – AGS Sydney Young Geotechnical Professional’s Night

The Young Geotechnical Professionals’ Night is an opportunity to see three selected presentations by young geotechnical professionals discussing interesting and challenging aspects of their work. After the presentations, you will have a chance to catch up with friends and the presenters over drinks and finger food, and see additional posters prepared by YGP’s. The following …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

AGS Research Award

As part of their ongoing support of academic institutions and students, the Sydney and Newcastle Chapters of the Australian Geomechanics Society are offering the prestigious AGS NSW Research Award for research in Geotechnical Engineering or Engineering Geology. The award aims to provide a forum for research students from NSW universities to showcase their research to …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
