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

摘要: 软弱夹层是控制岩体稳定的主要因素之一,对其研究的主要目的就是要给出正确、合理的力学强度参数.作 者在大量试验成果基础上,研究了某电站重力坝坝址区层状岩体中软弱夹层粒度成分和抗剪强度参数之间的相关 关系,并建立了各种稠度状态下的粒度成分和抗剪强度参数间的相关方程.同时结合《混凝土重力坝设计规范》中 提出的用粒度成分定量指标选取软弱结构面抗剪强度参数,对软弱结构面抗剪强度参数取值问题进行了探讨.
