本文根据高放废物处置库场址选择的基本要求，对区域地质及深部构造特征、新构造运动及地震分布规律进行了调查，确定北山南带地区为稳定区。在稳定区内根据处置库有利围岩的出露情况，结合岩体工程地质特征分析，初步选出了４个以花岗岩为主体的场址预选区。经综合分析，认为在４个场址预选区中，以Ｉ号预选区的条件最优，其次是Ⅱ号预选区，再次是Ⅲ号和Ⅳ号预选区。场址区的最后确定尚待进一步调查和论证。
Based on the basic requirements of HLR site selection, the paper investigates the regional geology, deep tectonic features, neotectonic movement and the distribution of earthquakes, and determines the northern Beishan area as a stable area. According to the appearance of the favorable surrounding rock in the reservoir and the analysis of engineering geological features of the rock mass in the stability area, four preliminary preselected areas with granite as the main part were selected. After a comprehensive analysis, it is considered that among the four pre-selection sites, the pre-selection zone I is the best, followed by the pre-selection zone II and the pre-selection zone III and IV again. The final determination of the site area pending further investigation and demonstration.
