江苏地区强震观测30年

Thirty years of strong motion observations in Jiangsu Province

从1972年原国家地震局南京地震大队与原国家地震局工程力学研究所合作筹建长江大桥强震观测台网起至今，江苏省的强震观测已经走过了30年的路程。 30年中，江苏强震台网在1974年溧阳地震、 1983年菏泽地震和1990年常熟地震中获得的有科学价值的地震记录，为大型桥梁空间动力性质的分析提供了实证资料，也为中国东部深井地震性质等重要科学问题的研究提供了实证资料。 江苏省地震局的科技人员还进行了大量与强震观测相关的科研工作。 至今，在江苏省及邻近地区已形成了固定观测与流动观测相结合的强震观测台网。 本文简要回顾了江苏强震观测30年历程，并展望了未来发展的前景。

The strong motion observations in Jiangsu Province have been on its way ahead for thirty years since 1972 when preparations were started for the building of the Strong Motion Observation Network of the Great Nanjing Yangtse Bridge by the former Nanjing Seismological Brigade，State Seismological Bureau，in coop eration with the Institute of Engineering Mechanics，State Seismological Bureau During the 30 years，the Jiangsu Strong Motion Observation Network has obtaine d seismic records of scientific value for the 1974 Liyang earthquake，the 1983 He ze earthquake and the 1990 Changshu-Taicang earthquake，thus provided observatio nal data for the investigation of some important scientific problems such as ana lysis of spacial dynamic behaviour of large bridges，the seismic behaviour of de ep mines in East China etc. The scientific and technical personnel in the Seismo logical Bureau of Jiangsu Province has also carried out numerous scientific rese arch work related to strong motion observations. Now，a strong motion observation network combining permanent observations with mobile observations has been formed in Jiangsu Province and its neighbouring area. The present paper briefly reviews the 30-year course of the strong motion observations in Jiangsu Province and looks into the prospects of its future development.
