摘要/Abstract

摘要： 以某地下水封储油洞库为工程背景，采用FLAC^3D数值模拟软件分析了施工期与运营期地下水渗流场的分布规律，并比较了裂隙岩体渗流各向同性与各向异性两种工况下孔隙水压力分布的差异，最后计算了围岩渗水量.结果表明，人工水幕系统对于保证洞库水封起到至关重要的作用；采用裂隙岩体渗流各向同性评估洞库间岩柱的稳定性更为安全；利用数值模拟方法计算得到施工期及运营期单洞库渗流量分别为1130m³/d和775m³/d.

关键词: 水封储油洞库, 人工水幕, 渗流场, 渗流各向异性, 渗流量

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
