Measured ground response to EPBM tunnelling in London Clay, webinar

About this event

The password for all the sessions is ice2021.

The twin-bore Crossrail tunnels under western and central London were mostly constructed in London Clay using earth-pressure-balance machines (EPBMs). The tunnelling-induced ground response, in terms of surface and subsurface displacements, as well as changes in pore water pressure and total horizontal stress, was measured at a ‘greenfield’ research monitoring site in Hyde Park.

The key findings from the field research have been published in three Géotechnique papers and two discussion paper contributions have been received. The papers provide a comprehensive and unique field monitoring case history of the short-term ground response to EPBM tunnelling in London Clay, making them invaluable for assessing ground response to tunnelling and validating future numerical analyses.

In this webinar the speakers will present key aspects of the measured ground response caused by the different stages of the tunnel construction for each of the two EPBMs, with an emphasis on the interpretation of the monitoring data in relation to various EPBM operations. The importance of a thorough understanding of the construction process to the accurate interpretation of monitoring data is highlighted.

Jamie Standing

Jamie Standing

Reader in Ground Engineering, Department of Civil and Environmental Engineering, Imperial College London

Jamie Standing is a chartered civil engineer who worked for a number of years in practice before moving to academia. His main research interests are in the areas of soil-structure interaction (tunnels, deep excavations, piles, soil nails), field monitoring and instrumentation, historic structures, small-scale modelling, unsaturated soil mechanics and laboratory testing of soils.

He has run major tunnelling research projects associated with: Jubilee Line Extension (greenfield sites and numerous building interactions); CTRL (effect of tunnelling on piled foundations) and Crossrail (effect of tunnelling on existing cast iron lined tunnels).

He is a member of TC204 (ISSMGE Underground Construction in Soft Ground) and was secretary from 2001 to 2012 and is also a member of TC220 (Field Monitoring in Geotechnical Engineering) and TC301 (Preservation of monuments and historic sites).

He has served on the executive committees of the BGA (twice) and BTS and also the editorial panels of Geotechnique and Quarterly Journal of Engineering Geology. He delivered the Géotechnique lecture in 2009.
