Abstract
This Study aims at rock Slopes Stability for formation in limb northـeastern poor anticline (Fatha, Injana and Mukdadyah). In (5) Stations, representing all types of failures (taken place and possible). General Survey for rock Slopes included Classification and engineering description according to [1][2]. The slopes in the area are Classified based on the direction of the Strike Slopes and Strike of beds into Parallel and Oblique Lateral Slopes according to [3] Classification and the Slope Types are Concordant Slope and discordant Slope.
The main modes of Failures involved rock Fall and Toppling. The Plane Sliding possible with existence conditions must occurrence of Failure. In addition to rolling and Slumping Which Some times Follows the above mentioned Modes of Failures. The main reasons for Failures occurring are differential Weathering Which Cause to over hanging Slopes by under Cutting in addition to the discontinuities in rocks Masses.
