BGA Touring Lecture - Practical use of shear wave velocity measurements in clay with a focus on UK and Irish clays


Dr. Mike Long of University College Dublin

25th Apr 2023 18:00 hours

The Terrace, 3 Wellington Place, Leeds, LS1 4AP


The main objective of this event is to promote use of shear wave velocity (Vs) measurements as a compliment to standard CPTU, SPT and other in situ test data.

Recent developments techniques for measuring Vs, e.g. SCPTU and MASW are described. Correlations between Vs and CPTU data and also with a variety of soil properties can be very powerful. However these correlations should ideally be local and only applied to other soils and areas with great caution. An exception might be for correlation between Vs and pre-consolidation stress pc'. Use of Vs data to help assess sample disturbance and for the prediction of settlement of footings is described.

Some future outlooks including dealing with lateral variability and anisotropy are discussed.

Speaker Biography

Mike is a civil engineering graduate of University College Cork and subsequently University College Dublin. Having first spent 11 years or so in industry, mostly with ARUP, he has been a lecturer in geotechnics at UCD since 1996 and a visiting professor at NTNU, Trondheim, Norway.

His main research interests comprise the characterisation of natural soils and the behaviour of deep basements in urban areas.
