摘要

在总结现有烈度计算方法的基础上,通过比较中国地震烈度评定表和台湾烈度评定表,提出以水平向地震动峰值加速度为标准的震动烈度表。表中采用1～10度共10级划分方式,每度都有定量标准与之对应。作者以福建省地震监测台网记录到的福建顺昌ML4.9地震和永春ML4.7地震为例采用以上震动烈度标准进行了分析计算,并与其他烈度计算方法及现场烈度调查结果进行比较,说明利用地震台网资料快速评定震动烈度的思路是可行的,评定结果可为政府应急救灾和民众了解大致震害程度提供重要信息。
This paper summaries the methods of intensity calculation used nowadays.We compare the intensity assess form used in China mainland and intensity assess form used in Taiwan region,we select the peak ground motion of horizontal acceleration(PGA) as our criterion and define a new assess form which has 10 levels and each level has certain PGA bound.Also we use this form and analyse the shaking intensity distribution of Shunchang ML4.9 earthquake and Yongchun ML4.7 earthquake based on records received by SMNF (Seismic Monitoring Network of Fujian province).Then we compare our results with other methods and results obtained by fieldwork.These researchs shows that rapid shaking intensity assess based on monitoring network records is feasible.Our results may provide government and public with important information for urgency and understanding the main breakage caused by the earthquakes.
