52nd Rankine Lecture (2012): 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

Use And Abuse Of Springs To Model Foundations

Springs are widely used in structural modelling packages to represent the stiffness response of foundations. This method is a significant improvement on models which assume the foundation is a rigid fixed or pinned support, and assigning a foundation stiffness is essential to enable structural models to better identify load re-distribution and deflection induced stresses in …more

Low level construction vibrations in residential structures

The first part of the presentation will examine the response of residential structures to low level vibrations by reviewing a comprehensive experimental program, which included a unique shaking-table study of a full-scale single-storey brick-veneer house subjected to 500+ vibrations, with Peak Particle Velocities (PPVs) ranging from 0.2 mm/s to about 400 mm/s (with interesting observations). …more

D.H. Trollope Medal 2010 ‐ Solutions for Oil and Gas Extraction from Shallow to Deep Water Resources

This lecture will describe rational mechanism‐based design approaches for foundations and anchors for supporting rigs and floating facilities in the frontiers of offshore oil and gas development, with more complex soil conditions at the seabed. In shallow waters, oil and gas exploration and production mostly rely on the stability of jack‐up rigs. The revealed soil …more

Sustainability and Resiliency Implications of Underground Structures

While underground construction for civil and military and mining purposes has existed for thousands of years, the conscious use of underground space to house a variety of infrastructure and special purpose facilities has only blossomed in the past 100 years. Today, in major urban areas, the growing population and very limited land area are driving …more

E.H. Davis Lecture – 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

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

Retrofitting graded chimney drain using bio-polymer slurry at Hays Creek Dam, New Zealand

Safety review studies showed that the Hays Creek Dam was prone to an uncontrolled piping failure during or after an earthquake due to filter incompatibility between the clay core and shell material. The discussion is in regard to the geotechnical aspects that were dealt with the upgrading design and construction of this dam in 1993 …more

Woodside’s North West Shelf Pile Foundations and North Rankin B Installation

Woodside Energy Ltd is Australia’s largest independent dedicated oil and gas company. It operates five piled platforms on the North West Shelf Australia: North Rankin A (1984), Goodwyn A (1995), Angel (2008), Pluto (2010) and North Rankin B (2012). All these platforms have piled foundations penetrating carbonate soils but there are particularities on the foundations …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
