摘要
高频地震反射波法能有效地进行隧道掌子面前方地质预报。为提高信号的信噪比 ,在傅立叶变换的基础上 ,引进小波变换理论 。
The result states clearly that the seismic reflection method of high frequency can effectively apply to geologic prefiguration in tunnel.In order to improve the signal resolution,based on the Fourier transform,the wavelet transform theory is recommended.Better geological result has been obtained in practice.
