Technological Soil Mechanics in Underground Construction

Abstract

The article is devoted to the application of the technological soil mechanics principles in the design and construction of underground structures, also in problematic soils – loose water-saturated sands. The definition of technological soil mechanics is given. The relevance of the research topic is justified. A quantitative assessment of the stress strain behavior (SSB) of the soil mass containing the support systems of deep pits, depending on the technology and sequence of work during underground construction, was made. The possibility of the SSB of ground mass managing during underground construction in order to select the most economical options for design and technological solutions is proved. Recommendations for SSB management of underground parts of buildings and structures, as well as the surrounding soil mass, based on the technological soil mechanics application are formulated.
