THE COMPRESSIVE STRENGTH OF PERMAFROST AND ICE IN THEIR NATURAL STATES (O VREMENNOM SOPROTIVLENII SZHATIYU VECHNOMERZLYKH GRUNTOV I L'DA ESTESTVENNOI STRUKTURY)
Laboratory and field tests of disturbed and undistrubed specimens of permafrost and active layer were conducted with the objective of determining the compressive strengths of the specimens at various temperatures, loading rates, and moisture contents. The specimens comprised several varieties of the...
