钻孔电视技术在三维地质建模中的应用
|
摘要
断层特征是岩体工程质量评价和三维地质建模的基础数据,但传统手段无法获得精确的深部断层产状。利用超声波钻孔电视技术可获得岩体深部断层的产状特征。基于钻孔电视技术和其他地质资料对中国高放废物地质处置地下实验室的推荐场址—甘肃北山新场花岗岩地段周边的断层特征进行研究,获得详实的断层特征数据,为推荐场址三维地质建模研究和地下实验室工程设计提供了参考数据。研究成果对区域基础地质研究具有重要指导意义。
The characteristics of fault is an important influence factor in the rock mass quality evaluation and 3 D geological modeling, engineering design of underground research laboratory.However, the dip and strike of fault in deep rock mass cannot be obtained by traditional methods. As one of the most direct and effective methods to detect fault in boreholes, borehole televiewer is used to obtain the dip and strike of fault in Xinchang pluton which has been confirmed the preferred site for URL on geological disposal of high-level radioactive waste in China. All the research results of fault provided meaning information for 3 D geological modeling, URL design and further geological research.
