A number of landslide and rock fall events in recent years have been connected with the warming permafrost in high mountain areas. This study investigates the shear strength of ice filled rock joints based on a series of direct shear tests. Artificial samples made of concrete with an idealised saw-tooth surface are used as described in detail by Günzel (2008). Two sample types are used: "concrete-ice" samples, imulating an infill thicker than the amplitude of thejoint roughness and "sandwich" samples where the ice filling is equal to the amplitude of the surface roughness (1mm).
