基于监测台网加速度信号分析的上海周边区域地震影响评价
Influence Evaluation of Earthquake in Surrounding Area of Shanghai by Analysis of Acceleration Signal of the Field-structure Seismological Array
摘要
Abstract
During the period from November 2021 to August 2023,there were five sensible earthquakes in the surrounding areas of Shanghai with magnitudes of 5.0,4.2,4.8,3.1 and 5.5 respectively in the sea area of Dafeng District,Yancheng City of Jiangsu Province,Tianning District,Changzhou City of Jiangsu Province,the sea area of the Yellow Sea,Qingpu District,Shanghai and Pingyuan County,Dezhou City of Shandong Province.The corresponding acceleration signals of the fields and typical structures were captured by the seismological array of Tongji University.The peak ground acceleration of the field,the peak floor acceleration of the typical structure and the duration of seismic acceleration signal are analyzed.The response spectrum characteristics of the earthquake signal are studied.Comparing with the first and second characteristic section of the design response spectrum curve,the influence of the five surrounding earthquakes on Shanghai area is discussed.关键词
