Determining the tensile strength of frozen ground
Conclusions Analysis and experimental research have confirmed that the indirect tension method can be used to find the nominally instantaneous tensile strength of frozen ground.Fracture of specimens of frozen ground is accompanied by formation of compaction nuclei at load transfer points; their appearance has a greater effect on the fracture of low-saturated cohesive soils and a lesser effect on sand, ice, and waterlogged cohesive soils.Equation (1) can be used to determine the nominally instantaneous tensile strength for the majority of soils obeying Eq. (7). Equation (8) can be used for calculating $ σ_{it} $ for cohesive, low-saturated soils.
