摘要
对岩石的扰动状态概念模型进行了具体的研究。分析了相对完整状态、完全调整状态的选择,根据岩石的内部微结构变化的特点修改了扰动函数,提出了一般形式的扰动状态本构方程的数值解法,并将理论计算结果与实验结果相比较,证明扰动状态概念是一种能较好模拟工程材料本构关系的方法。
The concept model of rock disturbance status is studied. The selection of relatively intact status and fully adjusted status are analyzed. The disturbance functions are revised based on the internal microscopic structural changes of the rock, a numerical solution is proposed for a constitutive equation of general disturbance status, and the result of theoretical calculation is compared with that of experiment, which demonstrates that the concept of disturbance status is a good method for simulating the constitutive relation of engineering materials.
