Geotechnical Analysis

The design of any geotechnical structure of significance requires the quantification of safety and in some cases movements. To achieve this the designer must perform calculations using some form of analysis. At present there are several forms of analysis available, all of which involve simplifications and approximations. This lecture will begin by briefly comparing these …more

Tomago Mineral Sands Mining Project

This project was recently acknowledged by the Association of Consulting Engineers Australia (ACEA) in their Engineering Excellence Awards for 1999. For the past 20 years Douglas Partners have been advisors the water authority (initially HWC, and subsequently DLWC) in monitoring the effects of mineral sands mining on the Tomago Sandbeds aquifer. The Sandbeds are also …more

Tunnels and Mines – Imaging Ahead of the Working Face with Seismic Reflection Tomography

Economic and safe rock excavation is critically dependent on detailed understanding of rock conditions beyond the working face. The latest advance has come in the area of seismic reflection tomographic imaging implemented from the opening during operations. The new technology allows three dimensional (3D) images of rock structure and condition to be rapidly obtained ahead …more

Shear Strength and Stiffness of Silty Sand

The stiffness and shear strength of clean sands have been studied extensively. However, natural sands generally contain significant amounts of silt and/or clay. The mechanical response of such soils is different from that of clean sands. This lecture addresses the effects of non-plastic fines on the small-strain stiffness and shear strength of sands. A series …more

The mysteries of blast induced ground vibrations

There are often anomalies between the expected level and the actual monitored level of blast induced ground vibrations. The main theme of this talk highlights the effect of the degree of confinement of an explosive charge on the magnitude of the shock wave transmitted through the ground. An analysis of the energy distribution of an …more

Assessment of regional landslide hazard

The process of assessment of the risk of landsliding involves consideration of the likelihood of a landslide event occurring and also the consequence of that event. A primary requirement is an estimation of the level of hazard that exists i.e. whether a landslide could occur, and if so, its probable frequency. This estimation is commonly …more

Geotechnical Anchoring Systems and GEWI Piles

The lecturer will first present a summary of the geotechnical anchoring systems offered by DYWIDAG-Systems International using bar and strand. The focus will then be on GEWI-Piles: a minipile system that uses steel Threadbars grouted in small drilled holes. The grout body encasing the Threadbar provides corrosion protection, enables load transfer into the rock or …more

Geotechnical Aspects of Kooragang Coal Terminal Stage 3 Expansion

The Stage 3 Expansion of the Kooragang Coal Terminal is a $345 million project, which will boost the coal exporting capacity of the Port of Newcastle from 77 million to 89 million tonnes per year. Port Waratah Coal Services appointed Bechtel Australia in July 1999 to design and construct the expansion. The key construction elements …more

Aspects of Development of Sydney Airport

The first significant development at Sydney Airport took place immediately after the Second World War when Cooks River was diverted to enable construction of the North-South and East-West Runways. This work was concluded in the late 1950’s by which time the present airport layout was essentially established. Since the early construction work at the Airport, …more

Mine Void Remediation for the West Charlestown Bypass, Newcastle

The earthworks associated with the West Charlestown Bypass in Newcastle are currently nearing completion. The project comprises 6km of dual carriageway motorway in an urban environment, extending from the Pacific Highway at Windale in the South to Charlestown Road, Kotara South, in the north. A 1km length of the Bypass, at the northern extent of …more

Maryland reactive Soils Field Site

Dr Stephen Fityus has a background in engineering geology and geotechnical engineering, from undergraduate studies in engineering and geology at the University of Newcastle. He worked for 4 years, mostly in the local geotechnical industry, before returning to the University of Newcastle to undertake his PhD on the topic of unsaturated soils, in which reactive …more

Seminars on Landslide Risk Management

In March 2000, the paper “Landslide Risk Management Concepts and Guidelines” was published in the journal Australian Geomechanics. The paper provides a benchmark for the terminology and methodology of Landslide Risk Management. The Coroner’s report on the 1997 Thredbo landslide recommended adoption of the paper. Emergency Management Australian (EMA) have identified the AGS 2000 Guidelines …more

E.H. Davis Lecture – Soil structure interaction

Often there has been a separation in the design of foundations for buildings into the structural component and the foundation. Structural engineers have tended to use simple soil models such as springs to represent the foundation, while foundation engineers have often neglected the foundation stiffness and treated the structural as being perfectly flexible. However, it …more

The environmental improvements of the Shingmun River, China

The Shing Mun River is a man-made flood water diversion channel constructed in the 1960s, passing through several major residential areas in the Kowloon / New Territories District of Hong Kong. Up until the early 1990s, the river has been the recipient of various forms of municipal and light industrial waste and discharge, resulting in …more

Construction of the Suez Canal

The earliest project to connect the Mediterranean Sea and the Red Sea dates back to 1920 BC. Construction of the Suez Canal, which commenced in 1859, has had a major impact on Egypts modern history, as it resulted in Egypt becoming backrupt in 1876, and being occupied in 1882 and later engaged in four wars. …more
