| 摘 要： | 用分段的岩石应力－应力全过程曲线作为本构关系，对圆形硐室受静水压力的状态作了分析，将受力岩层分成软化区和弹性区，用突变理论建立的势函数分析了突变模型，给出了发生岩爆准则，并与实测结果作对比，表明这种研究方法的有效性。

| Abstract: | Sections of a stress-strain curve of a complete rock failure process are regarded as constitutive relation. Based on which, the state of a circular chamber under hydrostatic pressure is analyzed.The stress zone is divided into softened area and elastic area. A model established on the basis of theory of catastrophe is discussed by potential function.A criterion for occurrence of rock burst is given and compared with measured data. It is proved that this theory is effective. |
