The time-frequency resolution has been improved, which meets the requirement of accurately extracting time-frequency distribution characteristics of nuclear power station blasting vibration response signals. Introduction of HHT algorithm into the data preprocessing of MP algorithm has successfully reduced the computational complexity of MP algorithm, and laid the foundation for large data analysis. Combined with the first phase project of Zhangzhou nuclear power station, the improved algorithm has been applied to analyze blasting vibration signals. The time-frequency characteristics of blasting vibration signals in the surrounding terrain and earth rock environment of the nuclear power station were obtained. This will provide reference for vibration monitoring and safety protection of blasting in the extension project.
