Analýza vybraných případových studií inženýrských objektů s problémovými inženýrskogeologickými poměry

Abstract

The major goal of the dissertation was to analyse selected case studies of engineering structures with problem engineering-geological conditions by means of implementing 5 studies. The dissertation emphasises the fact that one geological environment or engineering structure in the geological environment may behave differently considering diverse practical purposes and situations. This boundary condition was of the key importance in terms of selecting the situations. The subject of the dissertation were four geological environments and one engineering structure in the geological environment that were characterised from all possible engineering-geological points of view. Next, a methodology of selection of suitable situations was proposed, which presented case studies with various problem engineering-geological conditions (based on various purposes) in certain specific geological environments (selected were 4 environments) and one specifically selected engineering structure in the geological environment that had been shaped anthropogenically (quarry). The importance of the choice of the type localities was motivated by potential application in other localities of the Czech Republic and Slovakia. The four implemented studies concerned different behaviours of selected geological environments of loess (Study 1), fluvial (Study 2), deluvial (Study 3) and Neogene sediments (Study 4). The last study (Study 5) characterised an engineering structure situated in the geological environment of a quarry. The implemented studies within the dissertation contribute to one of the most crucial roles of engineering geology, i.e. point at the differences in the engineering-geological conditions, their diverse behaviours in different situations or geodynamic processes. The awareness of the differences in their behaviours is the most important contribution of the dissertation as it permits a comparison of several studies in one work. This may provide up-to-date information on the issue to engineering geologists, geotechnicians and designers.
