| 摘 要： | 根据冲击地压发生的力学条件和地质条件, 引入 (Ruina,1983年)单状态变量本构模型(Single state variable model, SSVM)对冲击地压的动力学行为和演化行为进行了描述。研究表明：模型中参数K， 对冲击地压系统动力学行为和状态变量演化行为贡献较大，而系统动力学行为和演化行为对 ，f初值的敏感性相对较低。模型模拟了冲击地压系统的粘滑特性和冲击地压系统的动力失稳过程，较好地解释了冲击地压的发生机理，为冲击地压失稳破坏的预测预报提供了理论依据。

| Abstract: | On the basis of mechanical conditions and geological circumstances of rockburst, the single state variable model is introduced to describe the dynamics characteristic and evolvement characteristic of rockburst. The research shows that the parameters K andb greatly affected the dynamics characteristic and evolvement characteristic of rockburst; andj, f contributed a little to the model. This model well simulated the stick-slip characteristic and the process of failure in rockburst system which explained the mechanism of rockburst and provided the theoretical foundation to forecast rockburst. |
