现在,多轴实验的重要性与迫切需要已得到极大的重视,这不仅仅是由于岩石的状态本来就是三维的,而且也由于现代数值方法和结构方程的发展有可能对复杂的三维几何问题进行分析。这些方法可提供真实的结果。而且当通过实验和现场试验准确地确定材料性质时,还可预测材料的性态。 Now the importance and urgency of multi-axis experiments have received a great deal of attention, not only because the state of the rock was inherently three-dimensional but also because of the potential for complex three-dimensional geometric problems due to the development of modern numerical methods and structural equations Analyze. These methods provide real results. And when the material properties are accurately determined through experiments and field tests, the behavior of the material can also be predicted.
