In the underground pressure environment,the damage and failure mechanism of rock under the action of multiblasting and other energetic disturbances are a basis of the long-term stability study of the underground engineering.Based on the analysis of the damage and deformation characteristics of rock under the action of disturbance rheological coupling,the improved Boggs model is built by introducing damage components and the concept of disturbance rheological coupling is proposed.The evolution mechanism of rock damage under the action of disturbance rheological coupling accumulated by dynamic perturbation stress wave energy is explored based on the analysis of mechanical mechanism of rock damage and failure under the action of disturbance rheological coupling defined in perturbation intensity and static stress.The test regression analysis of law of rock damage evolution caused by multiple dynamic disturbances under the action of moderate static stress will provide a new approach for the study of long-term stability of underground engineering construction.
