空气中声波在井下地震计记录强度的特征分析
Analysis of Noise Level at Borehole Seismometers Induced by Acoustic Waves in Air
摘要
Abstract
In this paper,based on synthetic seismograms,the effects of receiver depth,S wave velocity and attenuation structure on noise level are investigated.We find that the amplitude ratio of converted acoustic wave and P wave decreases exponentially with depth,when the receiver is deep enough and where S wave velocity is larger than acoustic wave velocity.Combined with the borehole seismic data of the 2015 Tianjin explosions,features of noise level are further discussed and examined,showing consistency with the characteristics of synthetic data.关键词
