Abstract:As for rare macrocharacters of landslide of soft rock slope in a mine, the mechanism that the residual tectonic stress impacted the slope and the mechanics of waterfilm of intercalated clay layer were studied. The result verifies that the macrocharacter of the slope slide is controlled by the relief of residual tectonics stress and waterfilm of the weak layer.
Key words: soft rock slope; residual stress; slope sliding; intercalated clay layer; effect of water film
