The Technique for Zoning by the Soil Strata Mechanical Stability Degree

Abstract

The safety of buildings and structures largely depends on the bearing capacity of soil foundations. Structurally unstable dispersed soils with unstable water-colloidal bonds are widespread in Russia, therefore, the issue of evaluating the mechanical stability of dispersed soils is relevant. The authors have developed a technique for zoning by the soil strata mechanical stability degree, the approbation of which is exemplified by a large construction site being designed. The deformation modulus has been used as the main criterion. The technique involves a series of sequential logical operations outlined herein. On the experimental site, areas with a low, medium, and high stability degree of the soil stratum and its engineering-geologic elements (EGE) have been identified. For sites with a low stability degree, recommendations for their development are given.
