N2 - The November 3, 2002 Denali-Alaska earthquake (M-w=7.9) caused significant liquefaction associated damage to various infrastructure built on fine-grained soils. The seismic response, liquefaction potential, and excess pore pressure generation of soils in cold regions, especially those of fine-grained nature, have not been studied thoroughly and therefore are not well-understood. This paper presents results from an extensive laboratory study on the characteristics of excess pore pressure generation and liquefaction potential of fine-grained soils. Laboratory-constituted soils specimens were tested in four categories: (1) tests on specimens subjected to no thermal conditioning or freeze-thaw cycles: (2) tests on specimens conditioned at 24, 5, 1, 0.5, and 0.2 degrees C; (3) tests on specimens subjected to 1-4 freeze-thaw cycles; and (4) tests on specimens conditioned at near-freezing temperatures of 0.5 and 0.2 degrees C through different freeze-thaw paths. Strain-controlled, undrained,
