Shake Table Modeling of Laterally Loaded Piles in Liquefiable Soils with a Frozen Crust

One of the important lessons learned from Alaska's major earthquakes in history is that the lateral spreading of frozen crust overlying liquefiable soils generated significant lateral forces and induced extensive bridge foundation damages. When the ground crust is frozen, its physical properties (including stiffness and shear strength) will change substantially. A shake table experiment was conducted to study the soil-pile interaction in liquefiable soils underlying a frozen crust. Cemented sand cured for a short period of time was found to possess similar mechanical properties of frozen soils and was used to simulate the frozen crust. Data collected from the shake table experiment was presented and analysed. The mechanism of frozen soil-pile interaction in liquefiable soils is discussed. It is concluded that it is important to account for the impact of frozen soil in the seismic design of bridge foundations in laterally spreading ground in cold regions.
