Overview

Infrastructure embankments (heaps) and cuttings (holes) are used to carry roads, railways, rivers and canals with a minimal need for changes in vertical alignment. In the cases of canals and railways in particular many of these earth structures were formed before the development of modern soil mechanics and before the introduction of techniques and equipment to produce reliable long-term behaviour. The change in condition of the materials used to construct them and their progressive deformation has a critical effect on their long-term serviceability and stability. To assess the serviceability and or stability of slopes it is essential to obtain reliable and accurate field measurements of pore water pressures and movements.

This event has been organised by the ICE Wales Cymru Ground Engineering Group

In recent years the International Organisation for Standardisation (ISO) has published a series of Standards that address geotechnical monitoring by field instrumentation, which cover methods of installing and reading the instruments that are used for measuring pore water pressures (piezometers) and deformations (inclinometers and extensometers).

Dr Andrew Ridley

Dr Andrew Ridley is Chair of the British Geotechnical Association and managing director of Geotechnical Observations Limited which he founded in 2000.

With over 40 years’ experience within the geotechnical sector of the civil engineering industry, he is known for his work on the measurement of soil suction (in situ and laboratory) for which he received a PhD from Imperial College London.

Andrew is currently the UK's representative on ISO TC182 WG2, which is writing international standards for geotechnical monitoring, a member of the British National Committee for standards in geotechnics B_526_3, Chair of ISSMGE TC220 Field Monitoring in Geomechanics and was Chair of the local organising committee for the 11th International Symposium on Field Monitoring in Geomechanics held at Imperial College London in September 2022.

In addition, Andrew was a member of the Steering Committee for CIRIA 550 Infrastructure Embankments – Condition Appraisal and Remedial Treatment, on the Editorial Panel of Geotechnical Engineering (Proceedings of the Institution of Civil Engineers) from 1998 to 2001 and was a member of the sub-committee to the Advisory Panel of Géotechnique for the 2011 Symposium in Print on Partial Saturation in Compacted Soils.
