甘肃北山岩体结构均质区划分方法的探讨

岩体结构均质区是针对实际工程特点而划定的成果，在实践过程中需要根据具体工程，抓住主要矛盾，选择最具影响性的要素作为划分依据。针对高放废物地质处置预选区两个重点问题--核素迁移和围岩稳定，合理确定了花岗岩体内结构均质区划分的依据以及与之相对应的划分方法。通过实际工程应用，认为得到的结果较为可靠，过程较易于实现，有一定的推广价值。

Discussion on zoning method of structural homogeneity of rock mass in Beishan of Gansu province

The zoning of structural homogeneity of rock mass is carried out according to the project features. In the process of practice, we must choose the elements which have great influence on the project used as the basis of zoning. The author rationally elects the elements and zoning method of structural homogeneity of rock mass in granite, based on the two key problems of the pre-selected area of high level radioactive waste, radionuclide migration and surrounding rock stability. By the applying of the project, the result is comparatively reliable; and the process comes true comparatively easily. So the method has certain extension value.
