【摘要】 在变质岩裸露山区进行数字地震勘探，主要采用地震资料的多次叠加数字处理法，经对地震反射波动学特征的分析研究，最终解决了有争论的Ｆ＿３及Ｆ＿８断层的倾向及深部延展关系。对邻近岩体与坝基岩体的Ｖｐ波测速对比，为评价该区坝址岩体工程地质提供了资料。更多还原

【Abstract】 In the subject of body-rock engineering study of the Yellow River Black mountain-pass Daliushudamsite, we have made digital seismic survey in mountainous-region whereupon metamorphic rockoutputted and utilizing the obtained seismic data explained the argumentative geological structure prob-lems. Enoughly taking the advantage of seismic data being mult-superimposed and by analyzing ,study-ing and discussing the wave movement factors character of seismic reflection. We finally made certainof the dig and the depth extention for F₃ , F₈ fault which was being with argument before. In while,made a Vp wave sed measutement comparison between dike bed-rock and its beyonds.For criticizingthe dike they-rock of the area provides geological and physical informations.更多还原
