High-speed Railway Geotechnical Problems

Distinguished Professor Daichao Sheng

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.

Distinguished Professor Daichao ShengDistinguished Professor of Civil Engineering and the Head of School of Civil and Environmental Engineering at University of Technology Sydney

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.
