This paper studies the anisotropic mechanical characteristics of the layered rock mass and the analysis method of macro mechanical parameters. It proposes an anisotropic material modules on the basis of ADINA

uses the partition grading macro mechanical parameters simulation method

combining with the theoretical idea of representative unit to make an analysis of anisotropic mechanical simulation and macro mechanical parameters of the two-mica-quartz schist in Danba hydropower station. From the results

the different schistose angle parameters and variation rules of the anisotropic mechanical characteristics of Danba schist are obtained. The results show that with the increasing of two-mica-quartz schist in Danba

the convergence rates of parallel and vertical schistosity deformation modulus and are not synchronized

amplitude increases with the increase of angle

it has a higher convergence rate. The trend of horizontal deformation modulus is more gentle

the variation of Poisson's ratio is just the opposite; with the schistose angle increasing

the mechanical parameters of the two-mica-quartz schist in Danba tend to the limit value obviously.
