| 摘 要： | 针对在非刚性加载条件下岩石破裂过程的非稳定性，用尖点突变模型研究其系统的失稳机制，采用ＨＰ．７０９０Ａ绘图测试系统实际测出了岩石试样在失稳破裂时载荷，位移的突跳特征；证实了系统失稳的阶段性；验证了突变理论应用于岩石失稳破裂的可靠性。

| Abstract: | Instability of rock specimen was studied experimentally with a cusp catastrophic model under nonrigid. The load-time, displacement-time and load-displacement curves of rock specimens were measured using HP. 7090A Plot-Measure system under unstable conditions. The results measured showed that they are fairly in agreement with the theoretical consideration proposed and verified reliability of catastrophe theory in application to the study of rock. |
