Stratigraphic-genetic complexes of the bedrock of Lviv city and their geotechnical propertiesZhyrnov, Pavlo (Avtor) Voloshyn, Petro (Avtor) stratigraphygenetic complexesfaciesgeotechnical propertiessoilsLvivThe geological basis of engineering geological surveys is based on age and genetic factors. The age is determined by the regional stratigraphic scheme. Identification of specific features and criteria of genetic subdivisions of rocks is the main task of studying the geological structure of the territory of Lviv city for geotechnical purposes. Stratigraphic and genetic complexes should be identified for this purpose based on the stratigraphic-genetic scheme of bedrock dissection. The bedrock of the Cretaceous and Neogene systems was separated into independent stratigraphic-genetic complexes by this principle and dissected into engineering-geological elements based on the application of stratigraphic and geotechnical research methods. The article describes each engineering-geological element with characteristic geotechnical properties and concludes their use as a basis for foundations of buildings and structures. The soils that are the most difficult in geotechnical terms are also analyzed, recommendations on foundation construction on problematic soils are given, and a set of engineering preparation measures aimed at improving the general engineering-geological situation in Lviv city are defined.Geološki zavod Slovenije20252025-12-23 03:58:41Neznano24863UDK: 551.1/.4ISSN pri članku: 0016-7789DOI: 10.5474/geologija.2025.013COBISS_ID: 262062851sl
