Other AbstractAmong the triggering factors of rock landslide, the water especially cracks water plays a most important and direct role. However, different with the soil landside, the effect of water in slope instability process for rock landslide is not clear. Here from the view of Fracture Mechanics, the mechanism of the cracks propagation and the slip surface development was researched. Then based on hydraulics formulas and using Sweden arc method, the influence of water to the stability of rock slope has been quantitatively studied. Finally, an example is given to prove the theory. The result indicates that the water in the big deep cracks is the main power to propagate crack and form sliding face, and the decrease of mechanical properties on sliding face and the hydraulic action on contact are the direst induced reasons.
