LINEAR VISCOELASTICITY STABILITY ANALYSIS OF BLUFF ROCK SLOPE

Instability destruction of bluff rock slope isclosely related to the creep of rock. With a given load, the delayed instability occurs after a period of time. Bytaking account of creep of rock and using the beam-pole model under the action ofgravity, the utmost height of bluff rock slope for different rheologymodels is derived.
