摘要

2005年11月26日在江西九江、瑞昌间发生了5.7级地震

震中烈度达7度强。瑞昌地震后

开展了对鄱阳湖口地区重大工程设计地震动参数的校核研究

分析了瑞昌地震后区域地震背景变化和地震震后活动趋势

对发震构造进行了综合判定

划分出了瑞昌潜在震源区

并针对该地区某大型桥梁进行了地震危险性分析和设计地震动工程参数的校核计算。结果表明

瑞昌地震是近场区外的中强地震

对鄱阳湖口地区设计地震动工程参数影响很小。本文的工作为破坏性地震震后重大工程设计地震动参数的校核工作提供了范例。

Abstract

A M5.7 earthquake occurred between Ruichang and Jiujiang in Nov.26

2005.Its epicential intensity was greater then 7.Then the earthquake engineering parameters at the outlet of Boyanghu Lake were checked.The seismotectonic of Ruichang earthquake and after-shock-tend was analyzed at first.A potential earthquake risk zone was shaped based on analyzing earthquake background and seismic activity around the outlet of Boyanghu Lake.Because the seismotectonic of Ruichang earthquake is about 40 km away from the outlet

the earthquake engineering parameters at the outlet basically do not change.The process of the work provides a model for post-earthqake reconstruction.
