Geotechnical and Environmental Research Group

 

After completing his MEng (Tianjin University) and BEng (Tongji University) in Geotechnical Engineering (both with Distinction) in China, Chuhan Deng completed PhD research on experimental soil mechanics and retaining structure design at Department of Engineering, University of Cambridge from 2016 to 2020, followed by postdoctoral research on environmentally-friendly urban underground space creation and offshore wind turbine foundations at Cambridge.

His research is characterised by applying fundamental mechanical principles to the behaviour of geotechnical systems, particularly utilising physical modelling. His PhD research results have been introduced in detail by his supervisor, Prof Haigh, in the 2021 Géotechnique Lecture (a biennial top lecture in geotechnical engineering). His research also shows direct engineering impact with an original design software Prowd (Program of Retaining Wall Design) being developed for industry and an innovative environmentally-friendly underground construction technique being utilised in the field.
