Abstract
On the caluculation for stability of sericite- schist, pretty and perfectly weatherd rocks were tested.
These tests were compression, tension, and shear test. In the shear test for rocks which is able to cut, the angle of schistosity to the direction of vertical stress were varied.
By this test c= 2.5kg/cm2 and φ=20°C were obtained, and caluculation was made by following fomula.
