• The extraction of reliable undisturbed samples of granular soils from below groundwater table for subsequent laboratory testing, is not possible by routine sampling methods. Consequently, during investigations for major, sensitive structures founded on such profiles, alternative sampling techniques such as in situ freezing and coring or dewatering and block sampling followed by laboratory freezing and coring, have to be considered. In both procedures, the soil is frozen at some stage.This paper presents the results of a study of the effect of freezing and thawing of granular soil on its static and cyclic strength and stress-strain behaviour. It is found that freezing and thawing leads to some degradation in the soil properties, but it is still recommended that these procedures may be used to obtain conservative values of the soil properties which are more relavant than those obtained from reconstituted specimens.
