[Abstract]:In the process of tunnel excavation, the geological information in front of the face plays an important role in the tunnel construction, especially in the area with complicated hydrological and geological conditions. If we can grasp the distribution of geological bad bodies in front of the face before construction and take corresponding measures, it is possible to avoid the occurrence of engineering accidents such as mud outburst, water gushing, collapse and so on. Therefore, it is very important to forecast the tunnel geology in the process of tunnel construction. This paper mainly studies the signal processing technology of tunnel geological advance prediction technology based on elastic wave method. The main contents are as follows: (1) in this paper, Fourier transform, The basic principles and numerical algorithms of discrete convolution and discrete correlation are derived in detail. (2) the relationship between S transform and wavelet transform and short time Fourier transform is analyzed in detail. At the same time, the numerical algorithms of S-transform and generalized S-transform are explained in detail. By comparing the spectrum of generalized S transform, short time Fourier transform and wavelet transform, it is shown that the generalized S transform has high time-frequency resolution. It is more suitable for data processing of seismic data. (3) in this paper, the basic theory and numerical algorithm of least square deconvolution and Gabor deconvolution are derived in detail. The relationship between Gabor deconvolution and square deconvolution is explained. (4) in this paper, Gabor deconvolution is used to compress the F-K filtered data to improve the longitudinal high resolution of the signal, and an engineering example is given to illustrate the effectiveness of the method.
