摘　　要：在高放废物深部地质处置过程中,围岩岩性、完整性及空间分布特征是构成天然屏障的关键地质因素。新疆某预选地段分布有大量花岗岩,场址评价工作初期开展了MT、CSAMT和磁法综合物探测量。据电性和磁性异常特征,初步查明花岗岩体的平面展布、底板埋深等分布特征,探测并验证了工区深大断裂的存在。3种物探方法相互印证,突显了综合物探方法的技术优势,为后续场址评价工作提供了参考。In the process of disposal of deep geology in high-level waste, the key factors of constitute a natural barrier are the rock’s lithology, integrity and its spatial distribution characteristics. The certain preselected area in Sinkiang has a huge number of granite. In the initial stage of site evaluation was carried out the integrated detection of MT, CSAMT and magnetic method. According to the anomaly characteristics of electrical and magnetic, it basically found the plane distribution of granite and growing distribution rules of buried depth. At the same time, we detected and tested the major dislocation in the deep. Three kinds of geophysical techniques to confirm each other which highlighted the advantages of the integrated geophysical exploration method and provided the references for subsequent site evaluation work.
