运用谱比法计算福建地区观测台网台站响应
|
摘要
场地动力特性对地震造成的破坏有着重要的影响。因此对场地进行动力特性分析,对于地震的监测预报、地震预警、工程抗震设防、地震勘探等具有十分重要的意义。本文主要结合福建地区现有地震观测台网,利用地脉动记录,采用较为简便的谱比方法(Nakamura方法)对福建地区观测台网中台站响应情况进行计算和分析。
Because the site synamic has enormous influence on the earthquake damage, analysis of the site synamic is of great significance to engineering fortification against earthquake, seismic exploration, monitoring and prediction. In this paper, we calculate site response of seismic network in Fujian region using spectral method based on the earth pulsayion data.
