UNIAXIAL TENSILE TEST FOR SOIL. FINAL REPORT

The tensile strength of soil is generally considered small for engineering applications. Yet there are a number of applications where even a small amount of tensile strength can have significant influence on computational results and actual structure performance. For example, the tensile strengths of clays are significant in problems involving low mean normal stresses. Motivation for studying tensile strength comes indirectly from the study of partially saturated soils, as the tensile strength is presumably derived from the suction potential of the soil. This report describes an apparatus for measuring strength of soils in direct tension. Data are presented for compacted Vicksburg silty clay for uniaxial tension and unconsolidated-undrained (Q) compression tests with a view toward proposing criteria to relate tensile and compressive strengths for partially saturated materials.
