Abstract
A basic model of the slide to slope failure is derived from three assumptions . The basic slide equation in tertiary creep is given as following: υ=a υ+bυ2. Here, υ is the velocity of displacement, υ the time differential of υ, a and b the constants. This equation expresses the acceleration mechanism of soil mass to slope failure and is available as a model of slope failure prediction. For friction coefficient (μ) theμ-υ relationship obtained shows the same tendency as the result of Dieterich, that is, μ decreases exponentially if υ increases. Lastly, the mutual relation of μ, υ and displacement (l) become clear by use of coefficients a, b and other physical parameters.
