摘　　要：基于我国某盐矿的地质条件,运用FLAC3D对在给定运行压力等条件下,矿柱宽度对储气库运行稳定性的影响进行了数值模拟分析。结果表明:矿柱宽度对储气库运行稳定性存在直接影响;储气库在一年的运行周期内,体积收敛率约为1%;在合理的储气库结构和运行压力下,矿柱宽度可以小于单个储气库的直径。A numerical simulation is done on the effect that safety pillar width has on gas storage running under given running pressure based on geological conditions of a salt mine in China, using software FLAC3D. The results show that： safety pillar width has direct effect on gas storage running; the volume closure ratio of gas storage is about one percent during one year running period; the safety pillar width could be less than diameter of cavern under the condition of reasonable gas storage formation and running pressure.
