| Popis: | Increased construction activities in cold regions require a better understanding of the behavior of frozen soil. Although in situ testing procedures are being improved or developed, the highly variable and complicated conditions usually encountered in the field make it difficult to formulate interpretations that are useful in practice. Controlled laboratory tests on frozen soils are helpful, therefore, in determining behavior indicative of diverse field conditions and will assist in establishing design information. This paper is a review of the procedures used and the difficulties encountered in the transportation, preparation, and storage of naturally and artificially frozen soil samples required for testing in the laboratory. The effective control of sample disturbance by temperature variation and sublimation and the need for further investigation as to their effect on the mechanical properties of frozen soil are discussed. |
