ABSTRACT
By equation (1) to obtain a new set of as a material new parameters for numerical calculation, when the soil slope conforms to a given critical failure state determination conditions, the corresponding F is called a minimum safety factor of slope. Where, are the stress tensor and the first invariant of the stress tensor second invariant bias, different α, k and c, are constants related to different α, k represents the type of the plane Yuan, Zha Shangyi, ZhengYing-ren, DENG Wei-dong et al article in detail and derivation.
