Abstract: Based on the analysis of method for establishing elastic and plastic damage evolution equation based on triaxial tests. The validity of the method is verified. Accordingly, an elastic and plastic equation is proposed for two classes of rock mass in Xiaoguanzhuang Iron Mine of the LuZhong Metallurgy Cooperation. With few parameters and clear physical concept, the equation is of great significance in numerical analysis of the tunnel in these rocks.
