摘　　要：在美国某地下核废料库的岩体力学分析中,现行研究均基于加载力学条件,未考虑岩体卸荷损伤。根据该地下核废料库实际加载区岩体和卸荷不同的力学条件,结合现行的加载岩体力学和卸荷岩体力学对地下核废料库的岩体变形进行综合分析。结果表明,综合分析结果与该地下核废料库的变形实测数据基本一致;研究结果可为该地下核废料库的支护提供支撑数据。When analyzing the rock mass of a underground nuclear waste repository, the current studies are all based on the loading mechanical condition, and the unloading damage of rock mass is unconsidered. According to the different mechanical condition of actual engineering rock mass of loading and unloading, this paper implements a comprehensive analysis on the rock mass deformation of underground nuclear waste repository through the combination of present loading and unloading rock mass mechanics. It is found that the results of comprehensive analysis and actual measured data on the rock mass deformation of underground nuclear waste repository are basically the same, which provide supporting data for the underground nuclear waste repository.
