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 ...

A New Method to Measure the Effective Porosity of Clays
The effective porosity is a required parameter for the mass flow rate calculations in groundwater hydrogeology. It is also a useful parameter in geotechnical engineering. In this paper, a methodology based on the tracer analysis technique is proposed to measure the effective porosity of clays. A test apparatus was developed and operational conditions were optimized to measure the effective ...

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 ...

Permafrost Thaw: Monitoring Ground Temperature to Assess Climate, Ecological, & Infrastructure Impacts
Permafrost is a critical component of the Earth’s cryosphere and plays a crucial role in regulating the planet’s climate. However, permafrost is vulnerable to changes in temperature, and as global temperatures rise, it is thawing at an alarming rate. This thawing process can lead to a cascade of environmental, ecological, and infrastructure impacts1. Permafrost temperature monitoring ...

What is the purpose of soil boring and borehole logging?
What is the purpose of soil boring? Soil boring is a practice of geotechnical investigations whose purpose is to determine the soils load-bearing capabilities, water table and chemical contamination. Boring is important because (1) it helps to determine the capacity of the soil to provide support to the structures on the surface, (2) it reveals the permeability of the soil to establish if it ...

Airborne Geophysical Solutions for Geotechnical Challenges
SUMMARY Assessing geological risk is a significant part of infrastructure planning and managing project cost overruns and delays are persistent challenges for engineers and project managers. Risks can be difficult to control given the high cost of detailed ground investigation programs using traditional approaches (i.e. geotechnical drillings). Airborne electromagnetic surveys (AEM) are ...

What is a bore log?
A bore log refers to a record detailing the in-situ conditions and aspects of geotechnical exploration activities such as drilling boreholes and mining. The log information needed to create a bore log is obtained through visual inspection of samples obtained from the geotechnical process. It is also obtained through geophysical measurements made along the borehole axis by using special logging ...
