| 摘 要： | 高分辨折射探测剖面近几年在我国的一些重要地学基础研究项目，特别是在中国地震局“十五” 期间开展的城市活断层探测及复杂上部地壳精细结构研究中得到了越来越广泛的应用.本文对在用传统有限差分方法处理高分辨折射地震资料时的缺陷及其改进算法的研究进展进行了较全面的讨论，对一些缺陷我们已给出了解决的方案，并已成功地应用于实际人工地震高分辨折射测量资料的分析处理，取得了较好的效果，还给出了将改进方法应用于深反射剖面初至波处理解释的一个应用实例，对于另一些缺陷我们在对国内外该领域研究现状调研的基础上，给出了目前我们正在进行中的解决方案.

| Abstract: | High resolution refraction profiles have been used more and more widely in some major basic geoscience research projects,especially the fine complex upper crust structure studies for urban active fault survey which has been gone on in CEA (China Earthquake Administration) during the Tenth Five Plan' of our country.In this paper,both the defects with traditional finite difference method to process the seismic data obtained from high resolution refraction profiles and the progress for their improving are discussed quite completely.The settling schemes for some defects,which have been successfully used to process and analyze the real seismic data from high resolution refraction profiles,are proposed and good results are achieved.Also,an applied example is given of processing and interpretation for first arrivals from a deep reflecting profile.Based on the studying and investigating from the domestic and abroad in this field,the settling schemes for other defects are under way at present. |
