4 关键块分析法在南克罗夫蒂矿的应用 4.1 关键块划分在本实例研究中采用了简单而有决定性的关键块分析法。然而,这种分析方法的局限性很快就暴露出来。很明显,如果节理组的产状发生变化,就会产生不同的块体元(几何结构)。对一些市场上可买到的关键块分析专用程序进行了修改。修改后的程序考虑了节理参数的变化,并用于上述分析。最终结果列于表3。 4.2 简单关键块体的稳定性分析简单关键块几何形体的稳定性分析是用多用户离散元(MUDEC)软件所提供的简单离散元程序完成的。这是用Fortran77语言编
THE APPLICATION OF KEYBOARD ANALYSIS METHOD IN THE SOUTH KROFFEI 4.1 Key Block Division A simple but decisive key block analysis method was used in this case study. However, the limitations of this method of analysis are quickly exposed. Obviously, if the joint group changes its shape, it will produce different block elements (geometry). A number of commercially available critical block analysis specific programs have been modified. The modified program takes into account changes in joint parameters and is used in the above analysis. The final result is shown in Table 3. 4.2 Stability Analysis of Simple Key Blocks The stability analysis of simple key block geometry is done using a simple discrete element program provided by the Multi-User Discrete Element (MUDEC) software. This is the Fortran77 language
