BGA Touring Lecture – Practical Use of Shear Wave Velocity Measurements in Clays with a Focus on UK and Irish Clays

Speakers: Dr Mike Long.

Past event: Please note this event information is displayed for informational purposes only.

Introduction

The Touring Lecture was established by the British Geotechnical Society (the predecessor to the BGA) in the 1980s to provide support to Regional Geotechnical Groups in the UK by bringing eminent geotechnical professionals from overseas to deliver a lecture on their particular expertise. The Lecture is biennial and is held at three venues around the country.

This event is hosted by the North West Geotechnical Group of the Institution of Civil Engineers.

Synopsis

The main objective of this event is to promotes 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 preconsolidation 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.
