The unique properties of frozen soils have posed special problems for engineers seeking to install stable structures in cold climates. Foundations, pipelines, and other structures subjected to high-frequency low-amplitude vibrations present special problems to the designer even when construction occurs in nonfrozen ground. When these dynamically loaded structures must be founded in frozen soil, the design problems become more complex. To produce a satisfactory design, reliable values of dynamic soil properties, such as soil stiffness, and damping, are required.
This paper presents the results of an investigation into the influence of confining pressure on the dynamic response of frozen Ottawa sand. In addition, the stiffness and damping ratio values obtained from a specimen of pure ice are reported herein.
