Abstract

Abstract: With the accumulation of four-component borehole strain observation data and the increase of seismic stations, it is important to improve the efficiency of processing and analysis of these data. Due to the high resolution of borehole strain observation data in an ultra-wide frequency band, borehole strain observation data are significant for earthquake and earthquake prediction research. Using the normal stress petal diagram to display the change of in-situ stress, we can not only qualitatively analyze the relative in-situ stress change at the station, but also quantitatively read the normal stress observed in any direction at a certain time. In this paper, this method is combined with data visualization technology and chart data combined with map display as the main body of the platform builds a visualization analysis platform of four-component strain data based on B/S architecture. This platform can intuitively display the spatiotemporal variation law of in-situ stress recorded by the borehole strain gauge and realize the visual analysis and interaction of borehole strain data and shared access by multiple users.

Key words: Four-component borehole strain observation data, Normal stress petal diagram, Data visualization
