Stability evaluation for slopes composed of thawing soils
Some methods are proposed for determination of the minimal strength characteristics of a thawing soil, i.e., cohesional coefficient of friction. These characteristics correspond to the shear strength at the thawing limit. Their values are considered both with and without the account of the active pore pressure influence. Based on the experimental data, the equation is derived for the calculation of minimal experimental strength characteristics of thawing clay depending on its physical propoerties. The slope stability coefficients are compared with that have been obtained for the minimal and maximal shear strength conditions.
