EASTABLISHING THE DAMAGE EVOLUTION EQUATION OF THE FRACTURED ROCKS BASED ON THE TRIAXIAL COMPRESSION TESTS
-
摘要: 分析了基于三轴试验的弹塑性损伤演化方程建立的方法 ,验证了采用该方法的合理性 ,并依此提出了鲁中冶金矿山公司小官庄铁矿两类破裂岩的弹塑性损伤演化方程 ,该方程参数少、物理意义明确 ,对该类围岩巷道进行数值计算分析具有重要意义。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.
