Research

Research Interests

Although Alberta is not generally considered as an earthquake-active zone, it is vital to educate the engineering communities with fundamentals of mitigation, preparedness, and recovery of earthquake hazards. Before joining University of Alberta, Dr Deng has been investigating an innovative rocking shallow foundation design methodology and soil stability using both physical modeling tools and numerical methods. Dr Deng is persistently interested in the research and education of geotechnical earthquake engineering covering the fields of,

• Dynamic soil-structure interaction,
• Pile foundations,
• Soil dynamics, and
• Permafrost engineering.

Dr. Deng's selected research projects are:

• Rocking Shallow Foundations for Improving Seismic Performance of Soil-Structure Systems, 2014 – 2018, NSERC – DG
• Innovative Rock Foundation for Earthquake Risk Mitigation, 2015 – 2017, UAlberta International
• Behaviour of Tapered Screw Pile Foundations in Unfrozen and Frozen Soils, 2015 – 2018, NSERC – CRD program
• In-situ Helical Pile Load Tests for CCMC Certification, 2014 – 2015

Dr. Deng is currently working on a few initiatives in geotechnical centrifuge modeling and worm-assisted tailings settling.
