Over the years, methods to assess cyclic liquefaction potential based on piezocone penetration tests (CPTu) have been developed. This paper presents a comparative study between three CPTu-based methodologies, mainly in terms of the normalization procedures of overburden stresses, equivalent clean sand resistance, and magnitude scaling factor (MSF). Four...
View ArticleSeveral regions in Brazil and the world suffer from the presence of collapsible soils. The development of theories for understanding the phenomenon is significant because the increase of water content is associated with several reasons (e.g., precipitation, rupture of sewage, and water systems). Although some theories explain the behavior of various typ...
View ArticleA geotechnical study based on characterization tests and seventy incremental loading onedimensional consolidation tests was carried out on high-quality undisturbed samples taken from Santos Harbor Channel subsoil near to Barnabé Island, where a pilot embankment was built. The characterization profiles revealed a stratigraphy following the pat...
View ArticleThis study aims to experimentally analyze the effect of fiber length and fiber content on shear strength and deformation properties of fiber reinforced soil by consolidated-undrained triaxial shear tests. The best mechanical properties are presented by the samples with 1.0 % fiber content and 3.09 cm fiber length. The stress-strain relationship of fiber...
