| 摘 要： | 分析了矿层底板失稳破坏发生突水的机制，根据底板突水的尖点突变特征、采用力学平衡和能量平衡方法和应用突变理论建立了矿层底板突水的突变模型。根据这一模型，应用尖点突变原理分析了承压水底板关键层失稳突水的力学机制。当满足关键层失稳的充要力学条件时，承压水底板有可能发生失稳突水。通过工程实例，用数值模拟证明了该理论分析方法是切实可行的，为底板突水预测研究奠定了可靠的理论基础。

| Abstract: | A mechanism for water inrush due to the floor instability and destruction is analyzed.According to the cusp catastrophe characteristics of water inrush from floor,using the method for the mechanics and energy balance and applying catastrophe theory,a catastrophic model for floor water inrush is established.According to the model,applying the cusp catastrophic theory the mechanics mechanism of water inrush is analyzed from key stratum of floor.Satisfying the sufficient mechanics condition for key stratum instability,a water inrush is likely to happen in the floor.By using an engineering example,the numerical simulation proves that the method for the theory analysis is practical and the method establishes a dependable foundation for research on predicting water inrush from floor. |
