Abstract

Abstract: As one of the important parts of the construction of the China Seismic Experimental Site, the borehole seismic observation system construction project has built an observation array of borehole near the Anninghe-Zemuhe fault, consisted of 10 borehole with a depth of 300 meters and 3 borehole with a depth of 1000 meters. By integrating the broadband seismometer and the Four-Gauge Borehole Strainmeter (FGBS), the co-point observation of seismic and strain is formed. The sampling rate of both FGBS and seismometers is 100 Hz, which is conducive to obtain high-quality seismic and strain seismic wave data of teleseism, regional earthquakes, and near-field microseisms. In this paper, based on the data of 300-meter borehole Tuowu, one of the earliest comprehensive seismic observation boreholes, we try to use the amplitude information of seismic waves and strain seismic waves, combining the theory of single-site estimation of phase velocity, to obtain the local Rayleigh wave phase velocity dispersion curve in the period of 20~125 s.

Key words: Borehole seismic comprehensive observation, High resolution strain seismic wave observation, Single-site phase velocity estimation, Phase velocity dispersion curve of Rayleigh wave
