| 摘 要： | 地震层析成像技术是通过观察地震波在岩体中的走时，反演观测区域波速分布的图像，以解决地质问题。层析成像处理后重建的图像，既包括了一些观测过程中的噪声，又包括了重建过程中的噪声。应用数字图像处理技术，可以改善图像的质量，突出图像中的有效信息，提高地震ＣＴ技术的应用效果。此法用于处理三峡工程和乌江构皮滩水利枢纽地质剖面资料，取得了较好的地质成果。

| Abstract: | The seismic computerized tomography is a technique of reestablishing the differential velocity distribution image of seismic wave in a region on the basis of different values indicating propagation time of seismic wave through different parts of rock mass in this region. A digital processing image by the seismic computerized comography will contain the noises occurring both in observation process and in computer processing process. Application of this digital image processing technique can improve the. quality of image,highlight the effective information of the image,and enhance the advantages of seismic computerized tomography.Application of this method to the geologic profilings at Three Gorges and Goupitan projects has achieved satisfactory results. |
