QuickBird影像在低中放废物处置场选取中的应用研究

Fault Structure Research in the Potential Repository Site for LILW Disposal Based on QuickBird Image

为了服务于低中放废物处置工程选址,采用精校正的高分辨率QuickBird影像作为主要数据源,运用遥感图像地质解译方法对处置场预选区内的断裂构造进行全面解译和识别,确定了断裂构造形迹的形态特征、尺度、走向和长度,圈定了预选区内所有岩脉并对其进行了初步分类。遥感解译结果与野外地质资料对比验证,对应性较好。在此基础上,划分出三个岩体完整性较好的区块用于放射性废物处置预选址。

In order to serve the low and intermediate level waste（LILW） disposal project site,the high-resolution QuickBird image after precision correction was used as the main data source,the remote sensing geological interpretation methods were taken to conduct a comprehensive interpretation and identification of faults in the pre-selection region,through which the morphological characteristics,scale,direction and length of faults were determined and all the dikes of the pre-selected region were delineated and classified preliminary.The remote sensing interpretation results show a good correspondence compared with the field geological data.On this basis,three blocks with good integrity were elected as preselected area for disposal of radioactive waste.
