Abstract

Abstract: Taking a water-sealed underground oil storage cavern as the engineering background， the numerical simulation software of FLAC^3D was adopted to analyze the distribution law of underground water seepage fields at the construction stage and operation stage. The difference of water pressure distribution in the fractured rockmass with and without seepage anisotropy was then compared. Finally， the seepage discharge of its surrounding rockmass was calculated. The results showed that the artificial water curtain system is of great importance to maintain the water sealing of caverns. Assuming the seepage of fractured rockmass， it is safer to evaluate the stability of rock pillars between caverns. The numerical simulation results of seepage discharge at the construction stage and operation stage are 1130m³/d and 775m³/d respectively.

Key words: water-sealed oil storage cavern, artificial water curtain, seepage field, seepage anisotropy, seepage discharge
