Abstract

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.
