| 摘 要： | 建立了矿井围岩2断层系统的准静态形变平衡方程, 将呈剪切破裂形式的断层失稳过程归结为折迭突变模型。模型可验证已有的岩体系统失稳破裂的临界条件, 还可给出系统恢复准静态形变的条件。用解析方式对断层失稳前兆阶段及失稳(震) 后阶段系统的稳定性作出符合物理意义和实际观察的描述。给出断层失稳前后的错距和围岩弹性能释放量计算公式。从中看到系统刚度比是刻划矿震强度恰当的系统内禀参数。分析结果可全部从已有的试验结果中得到验证。

| Abstract: | The equilibrium equation of surrounding rock mining fault system is established. The fault destablizing process with shear failure pattern belongs to fold catastrophe model. The model can be used to verify the known critical condition for rock system to destablize and give the condition for rock system to resume quasi statical state. The omen and post stages of rock burst of the surrounding rock fault system can be described by analytic way. The calculation formulae of fault offset and energy release of surrounding rocks are obtained. The obtained analysis results can be verified totally by the test results. |
