Northern Ireland has approximately 25,000 km of road network, which encompass a substantial number of large cuttings in Till. A slope failure of a deep cutting in Till at Dromore, along the A1 Belfast – Newry dual carriageway in Northern Ireland was reported by Hughes et al. (2007).
The factor postulated for instigating the slope failures was a reduction in long-term shear strength due to a combination of progressive deformations, strain-softening and dissipation of excess pore water pressure generated during the initial excavation, together with pore water pressure dynamics triggered by weather patterns; such progressive deformation is generally referred to as creep and fatigue.
A reliable estimation of geotechnical parameters is therefore necessary in order to accurately predict the performance of such structures.
This presentation therefore reports the investigations carried out to understand this time-dependent behaviour of overconsolidated Till using three strands of investigation: site characterisation, laboratory investigation and numerical modelling.
More specifically, a review of the pore pressure data is presented, as well as two methods of deducing in situ small strain stiffness, and stress path testing of reconstituted Till samples was carried out under static and dynamic pore water pressure conditions. The results of these laboratory and field stiffness investigations were used to calibrate field-scale hydrogeological and mechanical numerical models of the cutting in Lodgement Till at Loughbrickland.
This research was aimed at aiding asset owners, such as the Department of Infrastructure and Translink, in managing geotechnical risks, allowing them to develop assessment and adaption strategies to ensure the future safety and resilience of geotechnical transport assets.
Ruth is a Graduate Engineer for Amey who graduated from Queen's University Belfast with a MEng Civil Engineering in 2012, and will graduate in June 2018 with a PhD in Geotechnical Engineering. Ruth worked as a Research Fellow at Queen's University Belfast as a numerical modeler on an EPSRC funded project. From 2017, Ruth worked at the Water and Energy team at Jacobs Belfast, and recently joined the Geotechnical team at Amey.
Ruth is the current Chair of the ICE NI Graduate and Student committee, and sits on the ICE's Regional Executive Board, as well as the ICE Main committee during the 2017-2018 term. She has been on the ICE G&S committee since 2012. She is also a past committee member of the Northern Ireland Geotechnical Group.
Ruth Kelly (nee Harley) has published/ co-published a number of journal publications, peer reviewed conference papers and continues to publish. Having won the William Dearman QJEGH Young Author of the year award in 2016, she spent a year on the Editorial Board of the Quarterly Journal of Engineering Geology and Hydrogeology. Ruth has presented at a number of international conferences, including the Canadian Geotechnical Society conferences, and also to a number of industrial research partners, including the UKs Geotechnical Asset Owners Forum, and project sponsors.
Ruth is married, with 1 boy aged 2, and has is a keen pianist in her spare time.
