Abstract According to bifurcation specificities of displacement for compound rockmass slope affected by groundwater，the displacement formulas for rockmass slope in the process of progressive failure are derived，and the sufficient condition for the sudden instability of rockmass is given. In accordance with the characteristics and mechanism that groundwater softens rockmass of slide surface by physicochemical effect，the catastrophic displacement criterion for slope is established.
