中文摘要：
基于某地下水封储油洞库的地质条件，利用GeoStudio软件对其进行二维渗流分析，将裂隙岩体等效为连续介质，同时考虑渗透性较大的单条裂隙破碎带，探讨破碎带对洞室涌水量的影响。研究表明洞室上方裂隙破碎带的存在将增加洞室的涌水量，并随着破碎带宽度和裂隙倾角的增加而增加。对裂隙破碎带进行灌浆处理后，其渗透性降低，洞室的涌水量也明显减少。
英文摘要：
Based on the basic geological conditions of an underground unlined cavern for oil storage, two-dimensional seepage analysis software （GeoStudio） was employed to analyze the effect of fractured zone on water inflow of underground unlined cavern. The fractured rock mass was trea- ted as equivalent continuum medium, and single fracture zone with large hydraulic conductivity was embedded into the medium. The results show lhat the fracture zone at the top of the cavern increases the water inflow owing to the increase of the width and dip angle of the fracture zone. After the fracture zone grouting, its hydraulic conductivity decreased and groundwater inflow of the fractr~re zone reduces considerably.
