Abstract

Abstract

In this paper we investigated the damaging effect resulting from the vibration of pipeline gas explosion using a full-scale pipeline gas explosion test and, after data analysis, found that the attenuation of the pipeline vibration was more in line with the exponential distribution than with the classical power law distribution, and that the vibration intensity was not evenly distributed in the space, with a vibration enhancement in a specific direction. Adopting the improved MP-WVD algorithm, we also analyzed the time-frequency characteristics of the vibration in pipeline explosion and found that the main frequency range of vibration was 10−20 Hz, with a duration of 0.1−0.2 s as well as a multiple loading. Finally, we observed that the Rayleigh wave was stronger than the Love wave. These results can serve as reference for pipeline construction and accident investigation.
