Ambient noise as the new source for urban engineering seismology and earthquake engineering: a case study from Beijing metropolitan area

摘要: In highly populated urban centers, traditional seismic survey sources can no longer be properly applied due to restrictions in modern civilian life styles. The ambient vibration noise, including both microseisms and microtremor, though are generally weak but available anywhere anytime, an ideal supplementary source for conducting surveys engineering seismology earthquake engineering. This is fundamentally supported by advanced digital signal processing techniques effectively extracting the useful information out from noise. Thus, it essentially regarded as a passive method. this paper we first make brief of followed quick summary surveys. Then applications noise settings illustrated with examples Beijing metropolitan area. For example assessment site effect large area via microtremor observations. structural characterization typical reinforced concrete high-rise building using background By showing these argue that treated new economical, practical, particularly valuable projects hazard mitigation areas.
