Abstract
Based on nonlinear theory and measurements in situ, a method for predicting the blasting vibrations using the NARMAX model is proposed. This model can be identified by the input and output signals measured in situ. Then, the predicted signal can be calculated at the specific measurement location using the identified NARMAX model. In addition, the blasting scheme can be optimized based on the predicted results to control the blasting vibration. The proposed method has been verified by a hammer impact test, and applied in a newly tunnel construction project. The results show that the method features convenient application, high precision and can provide scientific support and optimization for blasting operations.
