报告人简介

Nicole Metje is Professor of Infrastructure Monitoring and Head of Enterprise, Engagement and Impact within the School of Engineering at the University of Birmingham, UK. She is also the Director for Sensors of the National Buried Infrastructure Facility (NBIF) part of the UK Collaboratorium for Research on Infrastructure and Cities. Professor Metje leads the Geophysics research of the Birmingham-led Quantum Technologies Hub for Sensors and Timing. Nicole works closely with industry through twelve jointly funded research projects developing sensors and novel processing methods to see through the ground to ensure that any excavation is safer and results in fewer delays. Nicole is a Member of the Chartered Institution of Civil Engineering Surveyors and the American Society of Civil Engineers. She leads the UK’s contribution to the ASCE Utility Standards and the US Transportation Research Board Utility Committees, was the only academic on the BSI’s PAS128 and PAS256 Steering Committees, is a member of the Institution of Civil Engineering Surveyors’ Utilities and Subsurface Mapping Panel. Her paper on assessing the impact of PAS128 in the UK has won the ICE’s James Hill prize in 2021.

报告简介

Unforeseen ground conditions are the biggest contributor to civil engineering project overruns and increased costs. This is also coupled with inaccurate information of the location of buried objects such as pipes, cables, mineshafts or solution features. A range of intrusive as well as non-intrusive methods exit to look through the ground. In the case of intrusive methods, these are expensive and time consuming and while revealing a great detail about the subsurface locally, they are no suitable to cover a large area. In the case of geophysical, non-intrusive, sensing technologies, they can provide some detail over a much larger area, but can suffer from resolution and depth penetration as well as the interpretation of the proxy data. To overcome these limitations, the University of Birmingham is developing a quantum technology gravity gradiometer which is more sensitive and can penetrate further into the ground. This talk focuses on providing some background of the existing approaches to look through the ground, highlights the novelty of using quantum technologies and provides an insight of some of the applications we have explored to date. Particular emphasis will be given to where the quantum technology sensor is superior to existing sensing technologies and the future direction of the research.
