Geologiczno-inżynierska charakterystyka gruntów antropogenicznych historycznej zabudowy Lwowa
Abstract
Engineering-geological characteristics of technogenic soil of the historical building of Lviv.
A b s t r a c t. In the article the conditions of occurrence, spatial distribution, genesis, composition and properties of technogenic soils in central part of Lviv were described. It was established that these soils cover the study area as a solid layer with thickness from 2.0–4.0 to 6.0–9.0 m. They are characterized by a high degree of spatial heterogeneity, low values of mechanical properties and specific sensitivity caused by the presence of ephemeral elements (makrooorganic substance, soluble salts etc.) in their composition that are very susceptible to changes in air-humidity regime.
