摘 要: 針對某采場軟巖邊坡大型滑坡破壞體罕見的宏觀破壞特征， 研究了邊坡開挖時殘余構造應力釋放對巖體的作用機制和泥化夾層水膜化效應的力學原理。研究結果表明， 該礦軟巖邊坡的破壞特征受控于殘余構造應力釋放及泥化夾層水膜化效應。
關鍵字: 軟巖邊坡； 殘余構造應力； 歪斜滑移； 泥化夾層； 水膜效應

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
