Characterization of collapsible soils due to saturation (Dept. C (structural) )

Abstract

This study is concerned with Collapsible soils which have significant volume decrease suddenly due to an increase in soil moisture content, with or without an increase in the in-situ stress level. Since the collapsible soils contain low levels of moisture content when they are formed naturally, they are considered to be such a problematic type of unsaturated soils. Reliable simple correlations between basic soil properties would be valuable because of the cost and difficulty of performing collapse tests either in the laboratory or in-situ. This study focuses on silty sand and sandy silt types of the collapsible soils. In order to fulfill the study objectives, a large database was developed from different researches works. The database contains information regarding basic soil properties of laboratory and field samples.
