In this article Kim discusses how wire-line logging tools can be used to measure physical parameters down boreholes.
– Investigating Instability – Writing for theGeotechnica this month are Martyn Brocklesby and Elizabeth Withington, Director and Senior Manager at Geotechnical Engineering. Last month Pete Reading provided details of the recent survey works carried out on the English South Coast focussing on cliff instability. This month Martyn and Liz provide a perspective on Geotechnical Engineering’s ground investigation work carried out on the affected area at Barton on Sea.
– How are you investigating your pipes and tunnels? – Writing for theGeotechnica this month is Geoff Acland, Business Manager of Arrow Geophysics Limited, a geophysical consultancy established in 2004 that provides advice on geophysical risk reduction for UK construction projects. In this, the third of a series of articles, Geoff explains the development of a specific technique for locating and investigating pipelines and tunnels at depth.
– Adaptive Oedometer Testing – In this month’s issue of theGeotechnica we have Dr Sean Rees of GDS Instruments writing the first in a series of articles for us. This month’s offering sees Dr Rees discuss the automation of oedometer testing and determination of the end of primary consolidation.
