定点形变观测在地震监测预报中具有独特优势,其观测数据可以反映与地震的孕育、发生直接相关的应力—应变信息。在日常地震监测工作中,大量定点形变数据需要进行分析和处理,为简化此项工作,设计开发一套基于MATLAB GUI的定点形变可视化分析系统,提供常见时频分析处理方法,具备数据导入、预处理、时频分析及数据输出等功能,用户界面操作简捷,可以满足日常计算和分析需求。
Fixed-point deformation observation has a unique advantage in earthquake monitoring and prediction, as its observation data can reflect the stress-strain information directly related to the preparation and occurrence of earthquakes. In the daily work of earthquake monitoring, a large amount of fixed-point deformation data needs to be analyzed and processed. In order to simplify this work, a visual analysis system for fixed-point deformation based on the MATLAB GUI is designed and developed, providing common time-frequency analysis and processing methods. It has functions including a data import module, a preprocessing module, a data output module and an image storage module. The user interface of the system is easy to operate and can meet the needs of daily calculation and analysis.
