Analysis of the influence of granular fractions on geotechnical characteristics for soils with similar behavior

Abstract

The paper presents a series of experimental tests related to the influence of granular fractions on geotechnical characteristics, using different methods of investigation and assessment. The soil samples selected for the study were collected from two different areas in Romania (Tulcea and Calafat), where similar soil categories were intercepted from the point of view of properties and behavior. Based on laboratory tests, the analysis consisted in establishing the predominant lithological types, the results being processed in order to reveal the variation of specific properties. The research has allowed conducting comparative and correlative analyses, based on the characteristics of soil types (silty and sandy loess), which led to outlined similarities of studied collapsible soils.
