摘　　要：为了使储油库设计洞距能够确保围岩稳定、施工运营安全以及经济上的合理,采用Hoek和Brown提出的地质强度指标(GSI)法,应用Hoek-Brown经验公式确定岩体力学参数。以辽宁某地下水封储油库工程储油洞室为研究对象,借助FLAC3D软件对围岩间距进行数值分析,利用位移判据对数值分析结果进行解释,进而判断洞室间距的合理性。最后指出:60 m间距方案可以满足工程整体稳定安全的要求,对工程实践具有一定的指导意义。In order to make the designed hole spacing to ensure the stability of surrounding rock, the security of construction and operation and the economic rationality, the Geological Strength Index （GSI） proposed by Hoek and Brown and the empirical formulas of Hoek-Brown are adopted to determine the mechanical parameters of rock mass. Taking the oil storage cavern of an underground water-sealed oil storage project in Liaoning as an example, numerical analysis is conducted for the surrounding rock spacing with FLAC3D software, displacement criterion is used to explain the analysis results, and then the rationality of the cavern spacing is judged. Finally, it is pointed that the program with 60 m spacing can realize required stability and safety of the overall project and it has a certain guiding significance for engineering practice. （7 Figures, 1 Table, 10 References）
