Evaluation of rock slope stability by different methods (Ünye,Ordu) [Kaya şev durayli{dotless}li{dotless}ǧi{dotless}ni{dotless}n farkli{dotless} yöntemlerle deǧerlendirilmesi (Ünye,Ordu)]

In this study,the stability of two rock slopes was evaluated by means of kinematic analysis,slope stability probability classification system (sspc),and slope mass rating (smr). the results of the kinematic analyses have revealed that planar,wedge and toppling failures would not occur in the analyzed slopes. based on the sspc orientation-dependent stability analysis,the slope-1 has 100% stability against the sliding failure,and over 95% stability against the toppling failure. the probability of stability of the slope-2 is over 95% against the sliding and toppling failures. the maximum possible heights and dip angles of the slopes were determined according to the orientation-independent stability analysis. based on the sspc orientation-independent stability analysis,the angles for a safe slope are proposed to be 75° for the slope-1 and 70° for the slope-2. according to the smr system,the stabilities of the slope-1 and the slope-2 were determined as partially stable and unstable
