The geotechnical group at PolyU strives to provide the best geotechnical education for
students and engineers, and conduct researches with the biggest impact to the society. The group members and their interests are
Equipped with Geology, Rock Mechanics and Soil Mechanics Laboratories, we have conducted and capable to conduct experimental researches relevant to real applications. Some of non-traditional experiments that we have conducted include subcritical cracking in rock panels for cladding wall, debris flow flume test, big size soil shear box for geotextile testing, big size rock joint shear box test (with the first MTS servo control machine in the world), hollow cylinder test, true triaxial test, cyclic triaxial test and Bender element test for dynamic properties, rock bridge experiments, fracture coalescence experiments, improved point load testing, multi-stage dead weight triaxial compression/creep experiments, and rockfall experiments using high-speed cameras.
Here are some of the examples of our past research topics: drilling at Longmenshan Frontal Fault at Bailu, shear strength of rock joints, development of SLOPE 2000 (slope stability software approved by Buildings Department), fibre optics sensor for piles and soil nails, creeping in clay, rockfall field test at Tung Shan Terrace, analysis of fossils found in Hong Kong, petrology studies for stone tools found in Sha Ha, pull-out testing of soil nail heads, application of GIS and GPS for landslide stability hazard, physical modeling test for tsunami observed at Phi-Phi Island in 2004 Indian Ocean tsunami, tsunami simulations, Discrete Element Analysis, granular flow experiments and simulations, theoretical analysis for point load tests, dynamic impacts and fragmentation of rock, surface ruptures induced by earthquakes, fracturing induced by steam simulations in oil sand, and shaking table tests for soil-pile-structure interactions.
