Research status of influencing factors and control technology of blasting vibration

In view of a series of harms caused by blasting vibration, it is of great significance to take scientific and reasonable blasting vibration control measures.According to the theory of blasting vibration attenuation, the influencing factors of blasting vibration are analyzed from blasting source conditions and propagation path.Then the research of several blasting vibration control techniques in theory, experiment and numerical simulation are summarized.Combined with the research status of blasting vibration safety criterion under different failure mechanisms, the development direction of blasting vibration research is pointed out: a fast and accurate evaluation system of blasting vibration advantage factors should be established; to use 3D numerical simulation to analyze vulnerable components of the building structure; the safety standard of blasting vibration with humanization should be formulated; the blasting vibration intelligent analysis system based on wireless network technology should be developed.
