Evaluation of Liquefaction Induced Lateral Spread from Recent Alaska Earthquakes

The objective of this project is to evaluate how the free-field lateral spread can be different for the Alaskan conditions, and how the pinning effects of abutments can be modeled when the crust is frozen. The work includes review of existing empirical models for lateral spread prediction, evaluation of lateral spread from Alaskan earthquakes, comparison of empirical model prediction and assessment of impacts on frozen ground crusts, and computer modeling of the impacts.
