Short- and Long-Term Slope Stability

Bases are presented for quantitative estimation of rates of creep displacements from results of rheologic testing of soil specimens in distortion and annular-shear devices, and also calculation of the stress-strain state of a slope by the finite-element method in an example of a creeping slope - Vorob'ev Hills in Moscow. Several zones where the degree of approximation to the limiting state is close to unity are noted from computational results. In these zones, the rate of creep displacements reaches 1.5 cm/year, which corresponds to results of field observations.
