摘要:地下水封石油洞库建设技术在我国刚刚起步,其水幕系统设计理念和方法还不成熟。
结合我国首个大型地下水封石油洞库工程,研究了水幕系统设计原则与连通性判断方法,分
析了水文地质条件对水封方式选用、水幕系统布置和水幕连通性测试的影响,并根据现场试
验结果,研究了水幕连通性判断方法,提出了改进的连通性测试方法。研究结论如下:地下
水封石油洞库水封方式的选择需充分考虑库区水文地质情况,而垂直水力梯度是判断洞库水
封性的重要参数;人工水封方式中水幕孔应尽量垂直于结构面走向布置;水幕连通性判断可
综合单孔注水试验与分区有效性试验结果进行,并考虑库区渗流场分布与变化规律对试验结
果影响;改进的水幕连通性测试方法能适用于不同水文地质条件下水幕孔连通性测试。本研
究可为地下水封石油洞库建水幕设计提供重要依据,并为岩体渗流特性研究提供不可多得的
工程实例。

Abstract: The construction technology of underground storage caverns was introduced into China in
few years ago. At present there is no extensive experience on the design and construction of the
curtaining system. Design principles and inter-connectivity testing method of groundwater curtaining
system were investigated with reference to a case study on a pilot underground crude oil storage
caverns in China. The influence of hyrogeological condition on the sealing method, arrangement
method of groundwater curtaining system and inter-connectivity testing method was obtained. From
field tests on the inter-connectivity of groundwater curtaining system for the pilot caverns, an improved
inter-connectivity testing procedure was proposed to determine the inter-connectivity of boreholes in
the curtaining system. From this study, it is found that the sealing method of underground storage
caverns depends on hydrogeological conditions of the sites, and vertical hydraulic gradient is an
important parameter for the sealing property of storage caverns. For artificial sealing method, the axles
of boreholes in groundwater curtaining system are suggested
