Spatial predictions of soil properties are needed for various purposes. However, the costs associated with soil sampling and laboratory analysis are substantial. One way to improve efficiencies is to combine measurement of soil properties with collec

Comparison of surface wave techniques to estimate shear wave velocity in a sand and gravel sequence: Holme Pierrepont, Nottingham, UK

Autor: Stephen Pearson, Gareth A. Williams, David Gunn, John Williams, M.G. Raines, Jonathan P. Busby

Publikováno v: Quarterly Journal of Engineering Geology and Hydrogeology. 45:139-160

This study evaluated the application of surface wave methods to aggregate variability and thickness determinations. We compared the results of field assessments of sand and gravel sequences using three surface wave survey approaches. The first was a

Refraction microtremor (ReMi) to determine the shear-wave velocity structure of the near surface and its application to aid detection of a backfilled mineshaft

Autor: Gareth A. Williams, M.G. Raines, S. Caunt, Dave J.R. Morgan, John Williams, David Gunn

Publikováno v: Quarterly Journal of Engineering Geology and Hydrogeology. 44:211-220

Passive refraction microtremor (ReMi) surveys utilize standard field seismic-refraction recording equipment and linear geophone arrays to record ambient background noise owing to microtremors caused by natural and anthropogenic activities. The techni

Publikováno v: Proceedings of the Institution of Civil Engineers - Geotechnical Engineering. 161:3-17

A detailed site characterisation was undertaken in order to assess methods that could be used to determine the depth and lateral extent of a potentially collapsible loessic brickearth deposit at a site in Kent. The investigation presented in this pap

Laboratory Measurement and Correction of Thermal Properties for Application to the Rock Mass

Autor: Lee Jones, David Gunn, Peter Hobbs, M.G. Raines, David Entwisle

Publikováno v: Geotechnical and Geological Engineering. 23:773-791

The requirement for quantitative thermal property data in assessing the performance of an engineered repository is identified. Experimental methods for the measurement of thermal conductivity, thermal expansivity and heat capacity are outlined and ty

A GIS for the planning of electrical earthing

Autor: Peter Hobbs, Jon Busby, K.A. Linley, Russell Lawley, N. Johnson, Peter Jackson, Joanna Zawadzka, T. Mayr, R. Palmer, S. Tucker, Helen Reeves, David Entwisle, M.G. Raines

When creating an electrical earth for a transformer with vertically driven earthing rods, problems can arise either because the ground is too hard or because the ground is too resistive to achieve the required earthing resistance. To assist in the pl

Using integrated near-surface geophysical surveys to aid mapping and interpretation of geology in an alluvial landscape within a 3D soil-geology framework

Autor: Oliver Kuras, M.G. Raines, D. Tragheim, Andreas Scheib, Holger Kessler, John Williams, Andrew Tye, Keith Ambrose

An integrated geological, geophysical and remote sensing survey was undertaken as part of the construction of a high-resolution 3D model of the shallow subsurface geology of part of the Trent Valley in Nottinghamshire, UK. The 3D model was created us
