Abstract

We studied some methodological questions forecast the physical and mechanical properties of soils array. Were analyzed the subsidence, physical, physic-mechanical properties of the Chernomorsky, Dofinovsky, Bugsky horizons of loesses. Total capacity of massive is 14,0 m, a state of incomplete water saturation (1985 – 2005).Considering two options for creating same scale of assessment for the state of humidity forecast the degradation of subsidence. Substantiate and prove the need to set the forecast state of the increments of natural moisture from the natural state to a state of full water saturation. Applying the three-part gradation condition where increasing humidity at 30 and 60 per cent corresponds to low and moderate change of state. Were confirmed dependence relative subsidence of loess on their physical condition and the specific fractions of particle size distribution, communication drawdown as a phenomenon with features microaggregate structure and its degradation. The collapse of the microaggregates occurs on the steps of the pressure close to the pressure of structural strength.Key words: loess, forecast, catastrophic process.
