RISShake Table Modeling of Pile Foundation Performance in Laterally Spreading Frozen Ground Crust Overlying Liquefiable Soils
Publisher: American Society of Civil Engineers
Abstract: One of the most important lessons learned from Alaska’s major earthquakes is that lateral spread of frozen ground crust overlying liquefiable soils induced extensive bridge foundation damage. A shake table experiment was ...
Long-Term Thermal Effects of Air Convection Embankments in Permafrost Zones: Case Study of the Qinghai–Tibet Railway, China
Publisher: American Society of Civil Engineers
Abstract: Long-term thermal effects of air convection embankments (ACEs) over 55-km-long permafrost zones along the Qinghai–Tibet railway were analyzed on the basis of 14-year records (22–216) of ground temperature. The results ...
Numerical Studies for the Thermal Regime of a High-Speed Railway Tunnel Considering Piston Action on Seasonally Frozen Regions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Piston action describes the phenomenon that air at the train nose is pushed forward by the increased pressure and air at the train rear is drawn forward by the decreased pressure when a train passes through a tunnel. The ...
