Equivalent Continuum Model for Jointed Rocks

摘要

The equivalent cotinuum model to be applied to asertain the constitutive of two or three dimensional problem in rock is presented in this paper. In the model, the rock cut by joints is treated as anisotropic material, the discontinuity of rock and irregularity of joint intermission are also can be simulated. A multi-lamina model is used to analyses rock mass strength. The rock's mechanical properties and stress distribution is take into accont.
