The current NSW state government is committed to the delivery of fast and high-speed railways in the state, with the short to medium-term focus on upgrading and optimising existing routes with target train speed of 200 km/hour, and the medium to long-term focus on building new routes with train speed over 250 km/hour. While it might be cost-effective and viable for Australia to import all transport components such as vehicles and control systems, we have to accommodate our ground conditions on which the high-speed railways are built. In this regards, geotechnical issues represent the key technical challenges for building high-speed railways in Australia. This talk presents some overseas perspectives of high-speed railway geotechnics, including some unique geotechnical problems like ground vibration and critical train speed, mud pumping and embankment degradation and cold region geotechnics

About the Speaker: Distinguished Professor Daichao Sheng

Daichao Sheng is a Distinguished Professor of Civil Engineering and the Head of School of Civil and Environmental Engineering at University of Technology Sydney (UTS) since 2019. Before his current role, he was a Professor of Geomechanics at the University of Newcastle during 1997-2019. His research interest spans computational geomechanics, unsaturated soils, transport geotechnics and environmental geotechnics. His involvement with high-speed railway stems from his conjoint position at the National Engineering Laboratory for High-Speed Railway Construction in China.
