摘要
介绍了在辽宁地区使用基于图像分析的双台相速度频散曲线提取方法进行相速度频散提取的工作,并选取了TSAnalysis软件操作实例详细展示提取过程。通过质量控制和筛选,获得了15~120s周期范围内的1100条独立双台路径相速度频散资料。
In this article,we introduced the study using the method based on the image analysis technique for the determination of dual stations Rayleigh wave phase velocity dispersion curves in Liaoning region.The example shows the extraction process in detail by using TSAnalysis.According to quality control and screening,we finally obtained more than 1100 phase velocity dispersion curves at periods ranging from 15s to 120s.
