Hydrodynamic Aspects in the Rotating Clyinder Erosivity Test
A comparison of different experimental installations used to study clay erosivity is presented. Flow in a rotating cylinder used in geotechnical laboratories is studied in detail. Analysis of the shear stress is presented, and conclusions are drawn as to the limitations of the quantitative evaluations of the critical shear stress in the rotating cylinder ...

The Preparation of Hollow Cylinder Specimens from Undisturbed Tube Samples of Soft Clay
The use of torsional-hollow cylinder testing apparatus for research into soil stress-strain behavior has grown over the past decade. Most studies have focused on sands or on cohesive materials reconstituted in the laboratory. Studies involving undisturbed soft clay have been neglected, in part due to the difficulties involved in specimen preparation.The present paper describes a procedure for the ...

The Use of a Centrifuge in Geotechnical Engineering Education
Geotechnical centrifuges have been seen to date principally as research machines. A role is now suggested in which centrifuges of modest size and cost can contribute usefully to the education and training of geotechnical engineers in college laboratories. One such machine, which has been used in teaching for 15 years, is described, and examples of the results of a series of simple demonstrations ...

Model Size Effects in Centrifuge Models of Granular Slope Instability
Two assumptions behind geotechnical laboratory testing are: first, that soil with grains small enough to behave as a continuum in a full-scale field situation will also behave as a continuum in a small laboratory test; and, second, that side boundary effects in a laboratory test are either negligible or, if not negligible, do not dominate behavior but are quantifiable so that a correction can be ...

Piezo Film Technology and Applications in Geotechnical Testing
Piezo films are thin, piezoelectric membranes that can be used both as source or as receiver. They may be adapted to a variety of in situ and laboratory geotechnical testing needs. This paper summarizes fundamental concepts in piezo film technology and the physical properties of this material. The principles behind common utilizations are reviewed, and three geotechnical applications are ...

The Use of Hall Effect Semiconductors in Geotechnical Instrumentation
For the past five years or so Hall effect semiconductors have been increasingly used in the geotechnical engineering laboratories at the University of Surrey. They have been incorporated as sensing elements in local radial and axial strain measuring devices, for the small-strain instrumentation of triaxial specimens, and in small diameter boundary normal and shear stress cells. Triaxial internal ...

An Interview with Warwick Wood (Managing Director) at EarthScience Information Systems Pty Ltd (EScIS): Environmental Data Management for Contractors
As an environmental data expert, can you share your perspective on the remediation field and how your technology can be leveraged to improve the way in which the industry works? One of the biggest challenges we see across our industry is the retention of environmental monitoring data and access to it. For instance, contractors often share data with multiple stakeholders, whether as part of a ...
