Abstract: The weak intercalated layer is an primary factor that controls the stability of rock masst. It is great significative that choose correct and rational parameters. On the basis of a lot of data from test, this paper studies the correlativity between granulometric composition and shearing strength parameter in sedimentary rock area, and that correlation equations are established in different consistence states. Finally, Bonding with "Design specification for concrete gravity dams", shearing streng
