In considering slope stability with accuracy, strength anisotrophy is one of most important factors. This paper describes slope stability analysis of weathered soil of Sangun metamorphic rock based on its strength anisotrophy. Sangun metamorphic rocks have a variety of schstosity. Undisturbed soil samples were sheared at different angles of shear surface to schistosity in box shear test apparatus. Main conclusions are as follows. Firstly, as the angle of shear surface to the schistosity, the internal friction angle increases and cohesion decreases. Secondly, safety factor obtained from Bishop method is significantly affected by the strength anisotrophy due to the schistosity.
