FIELD: construction on frozen grounds. SUBSTANCE: method for determination of amount of nonfrozen water in frozen grounds includes thawing of preliminarily frozen ground sample, continuous measurement of sample temperature during thawing with subsequent determination of amount of nonfrozen water by results of measurement, cooling of ground sample down to temperature below that of its start of thawing, simultaneous registration of sample temperature and time, and construction of graph of variation in time of logarithm of excessive temperature which is used to determine time and temperature of thawing end, and sought amount of nonfrozen water is determined by relation given in invention description. EFFECT: higher efficiency. 1 dwg
