甘肃北山预选区旧井地段断裂的分形特征——中国高放废物处置的潜在场址
|
摘要
以甘肃北山旧井地段的断裂为研究对象,对其进行了分形特征研究。在对该区的TM遥感影像进行线性构造解译的基础上,利用线性构造分布图,使用Box Flex方法,计算了旧井地段断裂的分维值,结果表明,旧井地段断裂具有分形特征,且分维值为1．466,在工程岩体质量分级中属于“好”的级别。通过此项研究,初步建立了旧井地段断裂分形特征的研究方法,评价了该地段花岗岩的岩体工程质量,为高放废物处置库的选址和场址评价提供了基础资料。
The fractal characteristic of the faults Jiujing section, Beishan area in Gansu Province is selected for this study. The fractal dimension value is calculated by using Box Flex method based on the fault distribution map, which is obtained from the geological lineament interpretation of high resolution TM satellite images in this area. Results show that fractal dimension value of the faults system is 1.466, and the rock mass quality of Jiujing section belongs to the class of "good". Based on this study, a method to study the fractal characteristics of the fracture system in Jiujing section is established, while the rock mass quality is evaluated. The results provide basic data for the site selection and site characterization for HLW repository in China.
