摘　　要：为了解马家岩水库右岸Z11,Z12,Z13岩层中软弱夹层的特性,在R1#平洞中对该软弱泥化夹层进行了现场直剪试验和室内中型直剪试验.通过分析试验成果,提出了该泥化夹层的力学设计参数,对工程设计和施工具有一定的指导意义.In order to find out the character of the weak intercalated layer in the formation of Z11,Z12,Z13 ,which lies on the right bank of the Majiayan reservoir, in the flat cavity R1# of the flabby intercalary stratum,some on_site and indoor tests are done with the flabby intercalary stratum. Some on_site direct shear tests and indoor mid_direct shear tests are also conducted. From this,the mechanistic design parameter is given, which has some directional meaning with the design and implementation of this project.
