摘 要: 針對(duì)某采場(chǎng)軟巖邊坡大型滑坡破壞體罕見(jiàn)的宏觀破壞特征， 研究了邊坡開(kāi)挖時(shí)殘余構(gòu)造應(yīng)力釋放對(duì)巖體的作用機(jī)制和泥化夾層水膜化效應(yīng)的力學(xué)原理。研究結(jié)果表明， 該礦軟巖邊坡的破壞特征受控于殘余構(gòu)造應(yīng)力釋放及泥化夾層水膜化效應(yīng)。

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
