结合某大型地下水封石油洞库工程，采用离散单元法，运用UDEC软件，模拟了不同工况下，不同倾角裂隙的存在对洞库渗流场的影响，并进而分析了在各渗流场情况下，洞库的水封效果的变化。结果表明：洞库周边的裂隙水压随角度增大而增大，在20°至40°中，裂隙水压快速增大，在40°至70°中，裂隙水压缓慢增大；相同水封措施对倾角较小的裂隙岩体的水封效果比大倾角裂隙岩体的水封效果差，要维持同等的水封效果就需要加大水幕洞水头，但是小倾角洞库的涌水量较大倾角洞库的小。

Combined with a large scale underground petroleum storage caverns Engineering, the paper took discrete element method and applied UDEC software to simulate the effect of different conditions and dip fractured rocks on seepage field .It also analyzed the effect of water seal in different seepage field conditions.The results shows that the fracture pressure surround cavern will increase with the increase of angle.From 20 to 40 degrees, the fissure water pressure increases quickly,but from 40 to 70 degrees, the fissure water pressure increases slowly.The effect of water seal in the fractured rock cavern of small angle is worse than that of fractured rock cavern with large angle.In order to maintain the water seal effect equally with the former, it is necessary to increase waterhead in the water curtain cave ,but the water in-flow in the fractured rock cavern with small angle is less than that with large angle.
