The study deals with experiments in drive sampling in frozen ground for the recovery of undisturbed soil samples. The drive-sampling experiments discussed in this paper were performed in frozen, fine-grained soils consisting of silts, clays, and fine sand. In addition, the drive sampling was performed in permafrost having temperatures ranging from approximately 29 to 31.5 degrees Fahrenheit. The drive method of sampling consists essentially of driving a tube or sampler into the soil and recovering the soil that enters the sampler as a result of the driving action. Driving of the sampler and subsequent withdrawal may be accomplished by power equipment or by manual procedures depending on the depth of the exploration. (Author)
