CONSTRUCTION PROPERTIES OF SUBSIDIBLE SOILS IN MONGOLIA UNDER CLIMATE CHANGE: PROBLEM AND SOLUTION
Main Article Content
Abstract
The main regional features of subsidence clay soils common in Mongolia are high porosity, low humidity and underfilling within the seasonal deep freezing due to their heaving and sublimation loosening. Using such soils as foundations for buildings and structures under conditions of increasing humidity is difficult at the design and construction stages, as well as during operation. This paper examines the results of analytical calculations to identify the dependence of a decrease in the physical and mechanical properties of subsidence soils on an increase in humidity and constructs the corresponding dependence graphs. Numerical modeling of the quantitative and qualitative assessment of the subsidence properties of sandy loam and loamy soils using the method of indirect signs and the probability of the formation of a subsidence process during soaking is also carried out.
