The constitutive model and equivalent deformation modulus of an arbitrary column in representative
elementary volume (REV) of fractured rock mass are derived. The deformation of fractured rock mass is composed
of the rock part and the fracture part. The elasto-visco-plastic property is considered in this model. For
the convenience in engineering practice, the complex elasto-visco-plastic model and its equivalent modulus are
degraded, and the rock is taken as an elastic body. By statistical analysis of the geometric positions of the column
and the fracture, the equivalent modulus of rock mass with arbitrary fractures is obtained.
