Abstract

In the UK road network, it is estimated that up to 4 million holes are cut each year in order to install or repair buried service pipes and cables, and it is important to identify the location of existing buried assets prior to such works if the numerous potential practical problems such as unforeseen costs and dangers for utility owners, contractors and road users are to be avoided. The Mapping the Underworld research team is attempting to develop the means to locate, map in 3-D and record the position of all buried utility assets without excavation. To realise this aim four different kinds of technologies are being studied: ground penetrating radar, acoustics, low frequency active electromagnetic fields and passive electromagnetic fields. All these techniques need waves to travel through the ground and they are affected by the ground properties. Geophysical techniques, such as the seismic surface wave technique, offer a non-intrusive and non-destructive way of analysing the ground and potentially providing measurements of geotechnical properties. However, we need to be careful in comprehending the relationships between geophysical techniques and geotechnical ground properties to ensure reliable interpretation and so as not to overrate the results that geophysics can accomplish.
