| 摘 要： | 2008年5月12日四川汶川发生M8．0大地震，江苏数字强震动台网固定观测台站、宿迁和溧阳断层观测存放台阵共获取该次地震有效强震动事件45个，计134条加速度记录。本文介绍了这些强震动记录分析处理的基本情况及其时域与频域的一些特点；编写SICalculate谱烈度计算程序和D2InterP二维插值程序，输入所获取的汶川地震26组实测强震动记录数据，得到该次地震在江苏地区的峰值加速度与谱烈度的等值线图，并就区域内地震影响场特征进行了初步研究。

| Abstract: | On May 12, 2008, the land of Jiangsu Province was shocked after the Wenchuan M 8.0 Earth- quake. Forty-five events consisting of 134 series of accelerations were recorded by two near-fault Temporary Storage Observation Arrays in Suqian and Liyang, and by fixed stations of Digital Strong Motion Observation Network of Jiangsu Province. These records have been processed to reveal their characteristics in time-domain and in frequency-domain. The computational spectrum intensity program SICalculate and the two-dimension interpolation program D2InterP have been implemented to compute the contours of the peak ground acceleration （PGA） and the spectrum intensity （SI） in Jiangsu with inputs from 26 groups of strong motion data recorded in the Wenchuan Earthquake. And the characteristics of the earthquake affect- ed field in Jiangsu have been studied preliminarily in this paper as well. |
