A STUDY ON THE DEFORMATION MECHANISM OF THE INCOMPETENT BEDS IN THE SHUIBUYA DAM SITE IN QINGJIANG RIVER
-
摘要: 清江水布垭坝址软弱夹层的变形机制为:(1)差异沉积作用造成了软弱夹层物质成分和结构构造上的差别,从本质上决定了软弱夹层的变形强度;(2)软沉积变形加强了软弱夹层物质的分异和软化;(3)构造活动导致软弱夹层发生多期次剪切滑动,使软弱夹层中的软弱物质泥化、叶理化并发生揉皱;使相对坚硬的结核和团块压扁、旋转和圆化。Abstract: The deformation mechanism of incompetent beds in the Shuibuya dam site may be summarized as follows:(1)The difference in composition and structure of the incompetent beds resulting from differential sedimentation determines essentilly their strength. (2)The deformation of soft sediments may facilitate their repeated shearsliding giving rise to the argillation, foliation and crenulation of the soft materials, and the flattening, rounding and rotation of the hard ones.
