    Abstract

    A direct-pull tension test was developed to study the behavior of compacted soils in total stress tension. A comprehensive series of tension and unconsolidated undrained compression tests was performed on Vicksburg silty clay; the data from these tests were supplemented with published data. Analysis of the data was based on relating the tensile strength parameter of the Griffith-Brace theory for brittle fracture to the suction-derived cohesion term of the Fredlund-Morgenstern failure law for partially saturated soils. Application of the analysis was demonstrated by relating tensile and compressive strengths to water content and void ratio.
