摘　　要：2001年6月上海台阵正式运行,上海台阵的建立提高了上海及周边地区的地震监测能力。本文着重在定位方法和震相判读上,充分利用上海台阵整体观测系统的优势和台阵独特的数据处理方法,对常熟2001年和2002年二次小地震序列进行了精确定位。对精确定位的结果进行了对比与分析,并以此为基础,对常熟地区及周边的地质构造等进行了解释与推断。The establishment of Shanghai Seismic Array （SSA）, which was officially put into operation in June 2001, greatly enhances the earthquake monitoring capability in Shanghai and its neighboring area. In this paper, by laying emphasis on the positioning method and phase identification, and making full use of the advantage of SSA observation system and the unique data processing method of array, we deal with the precise positioning of two minor earthquake sequences occurred in 2001-2002 in Changshu region, and carry out the comparison and analysis for the results of precise localization. As a result, we undertake interpretation and inference of the geologic structure in Changshu and its neighboring area.
