Application of Sample Element Method to Determine the Mechanical Parameters of Blocky Structure Crack Rock Mass
-
摘要: 在分析块状岩体的结构特征及影响其力学性能因素的基础上,根据大量野外调查及室内试验资料,对块状岩体进行分类,并建立相应的样本单元。采用数值分析方法模拟各类样本单元的大型三轴试验,实现了根据岩块参数获取块状裂隙岩体力学参数的目的。Abstract: Based on the analysis of the structure characteristics, influencing factor to the mechanical properties, the data of field surveys and indoor studies, the bolcky structure rock mass is classified and the relative sample element is built. The FEM is used to simulate the field large-size trail. The mechanical parameters of each sample element on the base of the mechanical parameters of block mass are abtained.
