Strength-deformation properties of Arctic silt

Hydrocarbon production activities in the Beaufort Sea require gravity structures capable of withstanding extremely large ice loads at sites where the subsea soil profile often consists of Arctic silts overlying relic permafrost. These conditions pose two unusual design problems: lack of experience with structures where horizontal forces constitute the dominant design load; and the highly variable and unique nature of Arctic silts compared to other offshore deposits. This paper summarizes classification and related properties of Arctic silts located in Harrison Bay, Alaska, and discusses the effect of temperature on results of consolidation tests. The main focus, however, is on undrained stress-strain-strength anisotropy of normally consolidated Arctic silt.
