| 摘 要： | 强震动观测数据通常由强震仪原始二进制加速度记录组成,在国内外相关强震数据库下载的强震记录均为解码、处理后的ASCII格式文本文件,非原始文件,记录格式不同,但均由数据头段和数据区2部分组成。以我国未校正加速度记录(UA)数据格式为例,探讨基于Matlab程序的强震数据处理技术,并识别记录的地震动特性,为强震数据多领域应用提供技术支持。

| Abstract: | The strong motion observation data are usually composed of the original binary acceleration records of the seismograph. The strong motion records downloaded from the relevant strong motion databases at home and abroad are all decoded and processed ASCⅡ format text files, which are not original files. The recording formats are different, but they are all composed of data header section and data area. Taking the unadjusted acceleration record (UA) data format in China as an example, this paper discusses the strong motion data processing technology based on Matlab program, and identifies the recorded ground motion characteristics, which provides technical support for the multi-field application of strong motion data. |
