微动台阵探测技术及其应用研究

The Exploration Technique for Microtremor Array and Its Application

介绍了利用微动台阵技术探测地壳浅层横波速度结构的仪器设备、观测系统、野外采集和数据处理方法 ,给出了用空间自相关方法测定相速度和浅层速度结构反演的实例。由于该方法不需要专门的震源 ,对于探测从地表到 3km深度范围的地层结构具有经济、快捷、应用范围广泛等优点 ,因此将成为一种新的具有很好应用前景的地球物理勘探方法。

The paper presents the studies of crustal shallow S\|wave velocity structure by using microtremor array technique,which including instrumentation,observation system and data processing.The example of phase velocity determination by spatial autocorrelation and inversion for shallow S\|wave velocity structure is introduced.The advantage of this method is no reqirement for special seismic sources for determining crustal structure at a depth of 0～3km.And it has a variety of applications in geophysical exploration.
