Culverts and Sewers – Buried but not forgotten

While largely out of sight and neglected for decades, the deteriorated state of our buried pipe infrastructure is now attracting considerable attention. An overview of a number of recent studies is presented, featuring both experimental and computational work to explore soil-pipe interaction and the performance of new, deteriorated, and repaired pipe systems. The presentation starts …more

Systems engineering the design and operations of municipal solid waste landfills to minimize contamination of groundwater

This talk discusses the need to adopt a systems engineering approach to the design and operations of municipal solid waste landfills. It discusses how the interaction between different components affects the performance of the entire systems and how, due to this interaction, the performance of the systems as a whole is much great than the …more

Stiffness at Small Strain – Research and Practice

The rapid development of computing power and of numerical modelling software over the past forty years has made sophisticated analysis of geotechnical problems accessible to most practising engineers. Typically computer packages now offer a wide range of constitutive models, which the design engineer needs to choose between, and then obtain parameters for. For those structures …more

Rock mass characterization; a vehicle to translate Geology into the design of Engineering Structures

The integration of site geology with engineering requirements is the basis of Engineering Geology. Despite the record of case histories and the development of field and laboratory investigation techniques, there continues to be a need to describe site geology in terms appropriate for the analyses of deformation and stability of ground in situ. Two developments …more

Concepts & Parameters Related to Ground Improvement Illustrated by Case Histories

The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee on Ground Improvement, has proposed a classification system of ground improvement techniques according to the general nature of the soil, (frictional or cohesive) and the inclusion or not of added material (http://www.bbri.be/go/tc17). This classification system has been detailed in the state of the …more

Recent Advances in the Application of Vertical Drains and Vacuum Preloading in Soft Soil Stabilisation

Pre-construction consolidation of soft formation soils by applying a surcharge load alone often takes a long time, thereby impacting the construction schedule. Moreover, attributed to the low permeability and high thickness of low-lying clay deposits, the required surcharge load to achieve more than 90% degree of consolidation can be excessively high over a prolonged period. …more

An Introduction to Cross-hole Sonic Logging of Concrete in Drilled Piers

Cross-hole Sonic Logging is a non-destructive quality assurance method that is used to assess the integrity of bored piles, barrettes and slurry walls, and is based on ultrasonic pulse velocity and attenuation measurements along the length of the structure. The technique is widely used in the United States of America, Europe and certain Asian countries. …more

A Case Study of Abandoned Mine Subsidence at Dominion, Nova Scotia, Canada, 2002-2003

Mining subsidence over shallow abandoned coal mine workings is unfortunately not an uncommon experience in the coalfields of North America, and there is a significant knowledge and literature base addressing the phenomenon and related issues. From time to time, however, a case history arises which is outside the more routine occurrence. This presentation looks at …more

Explaining Geotechnical Risks

Like many communications, those between developers and geotechnical engineers can be frustrating for both sides as often neither can fully understand the other. Geotechnical engineers are anxious to explain risks, but project developers are pre- occupied by a wide range of other worries and often can’t grasp the significance of geotechnical risks and don’t prioritise …more

Geotechnical and Pavement Engineering Aspects of the New Perth Bunbury Highway

The New Perth to Bunbury Highway located south of Perth is the largest road project that Main Roads Western Australia has ever undertaken. The project, delivered through an Alliance, comprises 70 km of dual carriageway freeway and highway with 23 bridges, of which 4 were incrementally launched across the larger rivers. The geotechnical ground conditions …more

On making the earth move!

This seminar will introduce a landslide experiment on a steep instrumented wooded slope along the River Rhine that didn’t fail during an extreme artificial rainfall event in October 2008. The reasons why, and actions taken, will be presented together with the successful repeat experiment in March 2009. In this case failure was achieved more or …more

Sources of Geotechnical Risk

The geotechnical risks that can impact upon projects result from a range of hazards associated with geological conditions and geological processes, but also from hazards associated with the geo-engineering process. For example, active faults identified during pre-feasibility studies will pose one type of hazard, whereas a management decision to limit the extent of a site …more

Geohazard Assessment for Critical Infrastructure Engineering

Engineering projects are susceptible to a wide range of geological and seismic hazards. Examples of these hazards include earthquakes, landslides, metastable soils, floods, volcanic eruptions, and other related phenomenon. Understanding the location, severity, and frequency of these hazards is of critical importance to selection of suitable development sites or asset corridors, as well as proper …more
