Abstract
In order to study the propagation and attenuation process of blasting seismic waves on high-rise buildings, taking the blasting construction of the entrance A of Xizhen Station of Qingdao Metro Line 1 as an example, the vibration velocity of the 33-story frame structure under the blasting construction condition were analyzed. The results show that: under the action of blasting seismic waves, the vertical vibration velocity of the building structure is greater than the horizontal direction; the vibration velocity of the underground structure of the building presents an oscillation trend, the vibration velocity of the above-ground structure decays rapidly, and there is an elevation amplification effect on the top floor; the research results have certain reference significance for urban blasting construction, monitoring, and seismic protection measures of high-rise buildings.
