用多道滤波接收函数法反演佛子岭台基的S波速度结构

Velocity Structure beneath Foziling Seismic Station from Teleseismic Receiver Function Estimated by Multi-channel Deconvolution

以佛子岭地震台数字化仪器记录到的远震数据为基础,应用多道反褶积方法分组提取邻近地震事件的接收函数,并选择合适的地层厚度将台站下方介质结构简化成关于S波速度的水平分层模型。以此对Ps转换波的接收函数进行共转换点偏移叠加,反演计算得到每个水平层中的S波速度值,并给出了佛子岭台台基下方一维S波速度结构图。

Based on the teleseismic data recorded by digital seismograph of Foziling seismic station. We designed a multi-channel deconvolution filter to calculate receiver function groups of nearby seismic events, and selected suitable strata thickness to simplify their structure, which is a model for S wave velocity on the horizontal levels. And we migrated these receiver function groups of P-s converted wave by the Common Conversion Point stacking method, inversed S wave velocities of every horizontal levels, and plot the figure of S wave velocity structure beneath Foziling Seismic Station.
