Composite Model and Effective Elastic Properties of Natural Rock Mass Material

The jointed rock mass is a kind of natural composite material existing widely in nature.This paper proposes the micro-mechanics model of the rock mass composite material containing joints.Homogenization method is used to calculate the effective elastic parameters of the rock mass with arbitrary joint angles and the relative width of the joints.The variation curves of equivalent elastic modulus versus the joint angle and the relative width of the joints of the rock mass are obtained.
