Numerical Modelling Of Dynamic Saturated Soil And Pore Fluid Interaction

Earthquake induced liquefaction has caused extensively damage to various cities and one of the most notable one is the damage caused to Christchurch on 22nd February 2011. Liquefaction occurs because of the interaction between the soil particles and its pore fluid. The seminar will describe the cause of liquefaction and the typical damage it causes. …more

Digital Photogrammetry, a Practical Tool for the Modern Geotechnical Practitioner – Applications for Mining and Civil Geotechnics

ABSTRACT Digital photogrammetry is revolutionizing the task of remote geotechnical mapping of jointed rock masses and has greatly increased in popularity and sophistication in recent years for this application. Less well known however, are the many other applications of this technology for geotechnical engineering and associated fields, including landslide mapping, slope monitoring, geological mapping, tunnel …more

Monthly Seminar – Jack Box Tunneling

ABSTRACT Already recipient of a major international engineering award, the jacked boxes comprise two 65m long concrete structures which were jacked beneath the main North Coast railway line (6 operating tracks) at Toombul in difficult ground conditions.  The operation was one of the largest of its type ever undertaken – each box weighing around 10,000 …more

Foundation Workshop – Logging of Core for Civil Geotechnical Purposes

COURSE OVERVIEW The course aims to (further) educate geologists, geotechnical/environmental engineers and geotechnicians who are tasked with logging drillhole core derived from a civil geotechnical investigation. No prior experience in logging rock core is assumed, the aim being to familiarise participants who may not have had much opportunity to log core in the field with …more

Foundation properties of variably weathered rock beneath a heavy mineral processing plant

This presentation covers an assessment of rock mass properties in a large foundation for a new Ball Mill at McArthur River Mine, Northern Territory, Australia. The results of geotechnical mapping in a substantial foundation excavation in a sequence of variably weathered meta-sediments are described. Deformation modulus values are evaluated using estimated UCS values and fracture …more

Geosynthetics in Road Pavement Design Methods

The use of geosynthetic materials such as geogrid, geotextile and geocomposite products in roads and pavements for reinforcement has been demonstrated to be a viable technology through studies conducted over many years. Research has shown the importance of design variables in the efficiency of geosynthetic materials. The use and specification of geosynthetics for pavement support …more

E.H. Davis Memorial Lecture 2012: 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
