Geotechnical

The geotechnical group’s interests range from fundamental to applied research in broad areas: constitutive and numerical modelling of static and cyclic saturated and unsaturated soil behaviour at various temperatures; multi-phase flow in soil; mechanical behaviour of granular soil; physico-chemical soil behaviour of clayey soil; soil testing techniques; dynamic soil properties; wave-based characterization of geomaterials; development of innovative geomaterials; geo-energy issues including energy pile foundation and off- shore foundation engineering, geo-environmental problems such as innovative membrane-free landfill covers and green slope engineering; onshore soil-structure interaction involving piles, tunnels, and deep excavation; and the risk and reliability modelling of geotechnical performance. The research is facilitated by the advanced HKUST geotechnical engineering laboratory as well as the state-of-the-art Geotechnical Centrifuge Facility (GCF) at HKUST, which is one of a kind in Hong Kong.
