地震作用下泉州古塔结构反应分析

Analysis of Seismic Effect on Ancient Pagodas at Quanzhou

摘要:

泉州一带历史上经常发生地震。1604年泉州曾发生大地震，地震烈度约为8度。开元寺的镇国塔的顶盖尖石在地震中坠下打坏了下面各层的部分石栏杆。但是，仁寿塔却毫无损坏。因此，本文通过大量计算和实测，分析在公元1604年泉州东北方向海里发生的一次强烈地震而幸存下来的石结构古塔抗震性能，并为以后塔体的维修及加固提供一些有用的数据。

Abstract:

Quanzhou has been an earthquake-prone area since ancient times. Based on a large amount of calculated and measured data, this paper analyzes the seismic performance of the ancient pagoda with stone structure which survived the strong earthquake in the sea northeast of Quanzhou in 1604 AD, and provides some useful data maintenance and strengthening of the pagoda.
