一引言为使面广量大的土应力资料,较可靠地反映地下应力的变化和排除自然因素或外界干扰的影响,我们对江阴县以至长江口地区四年多来数以万计的数据进行处理和筛选。处理的方法包括滑动法订正、单因子或多因子干扰相关差分分析,并在处理后的土应力曲线上标出震中距(R≤250公里的Ms≥3.0级震和R≥500公里的Ms≥5.0级的地震),以筛选出对地震前兆反映最佳或较好的若干组土应力测点资料,为震情分析的主要依据。
I. INTRODUCTION In order to make a large amount of large soil stress data more reliable to reflect the change of underground stress and to exclude the influence of natural factors or outside interference, we conducted tens of thousands of data for more than four years from Jiangyin and Changjiangkou areas Processing and screening. Methods include correction of slip method, single-factor or multi-factor interference-related differential analysis, and the epicenter distance (Ms≥3.0 magnitude R≤250 km) and Ms≥≥500 km 5.0 magnitude earthquake) to screen out the data of some groups of soil stress measuring points that best or better reflect the earthquake precursors, which is the main basis for the earthquake analysis.
