Abstract EN
This paper takes the Dizong tunnel engineering as its background.
Combined with the on-site monitoring data, the wavelet packet program based on MATLAB was compiled to study the vibration response of the four-story masonry building in a typical southwestern mountainous area of China under the blasting load.
The results showed that the maximum particle velocity increased to the 3rd floor and attenuation occurred on the 4th floor.
The particle velocity in the z-direction was the largest and should be paid attention.
The dominant frequency of the building showed a trend from high frequency to low frequency, the duration became short, and the acceleration decreased to the 4th floor.
With the increase of the building floor, the main frequency domain of the building decreased and then gradually tended to the low-frequency domain.
The high-frequency particle velocity gradually decreased, gathered to the low frequency, and developed from the dispersed multiband to the concentrated low-frequency band.
The total energy value of vibration increased to the 3rd floor and then decreased to the 4th floor.
The energy of the building was between 0 and 171.6 Hz.
The higher the floor was, the more concentrated the energy was in the low-frequency domain.
