Title: Distributed fiber optic sensing for infrastructure engineering
Design, construction, maintenance and upgrading of civil engineering infrastructure requires fresh thinking to minimize use of materials, energy and labor. This can only be achieved by understanding the actual performance of the infrastructure, both during its construction and throughout its design life. Recent advances in distributed sensing technologies such as fiber optic based sensing can radically change the quality and quantity of information we can get from civil engineering infrastructure. In this talk, several case studies using distributed fiber-optics sensors to understand the performance of tunnels, piles and underground construction in London, UK are presented. The value of the dense spatial and temporal data obtained from these sensor systems will be discussed.
Kenichi Soga is the Donald H. McLaughlin Professor of Mineral Engineering and a Chancellor’s Professor at the University of California, Berkeley. He obtained his BEng and MEng from Kyoto University in Japan and PhD from the University of California at Berkeley.He was Professor of Civil Engineering at the University of Cambridge before joining UC Berkeley in 2016. He has published more than 400 journal and conference papers in the area of infrastructure sensing, performance based design and maintenance of underground structures and energy geotechnics. He is a founding member of the Cambridge Centre for Smart Infrastructure and Construction (CSIC) based at Cambridge University. CSIC is an international center of excellence in sensors, data analysis and interpretation, and smart city systems,. He and his team have been developing sensing systems and data analysis tools to provide a platform for delivering data that enables smarter and proactive asset management decision-making, both during construction of new infrastructure and for existing structures. He is the editor-in-chief of the Institution of Civil Engineer’s Smart Infrastructure and Construction Journal and the chair of American Society of Civil Engineer Infrastructure Resilience Division’s Emerging Technologies Committee. He is a Fellow of the UK Royal Academy of Engineering and a Fellow of the Institution of Civil Engineers. He is the recipient of awards including George Stephenson Medal and Telford Gold Medal from the Institution of Civil Engineers and Walter L. Huber Civil Engineering Research Prize from the American Society of Civil Engineers.
