摘要

摘要: 为认识水封石油洞库区地下水位的动态变化过程，以黄岛地下水封石油洞库的基本地质条件为依据，采用饱和非饱和非恒定流数值分析方法，对水封油库在施工期和运行期可能出现工况下的地下水位变化情况进行了全过程数值仿真计算，分析了不同时期洞库区附近岩体的地下水位分布特点及变化过程。研究表明水封油库区内的地下水位变化过程主要受岩体渗透系数、洞库开挖方式和运行方式的影响；当洞库区岩体渗透系数大于 m/s 时，洞顶上方岩体中的地下水将被疏干，必须设置水幕系统来保证洞库的水封效果。

Abstract: To better understand the variation process of water table near the caverns, based on the basic geological conditions of Huangdao underground rock cavern for an oil storage project, the saturated and unsaturated non steady seepage numerical method is employed to simulate the variation of water table under different cases during the construction and operation periods. The distribution features and whole variation process of the water table near the caverns during different periods are analyzed. It indicates that the variation of water table due to the excavation of caverns is mainly influenced by the values of coefficient of permeability, excavated ways and operation ways of caverns. The water on the top of the caverns for oil storage will be drained off if the coefficient of permeability of rock mass is greater than 10 ? 10 ^{- 7}m/s . In this situation, the water curtain system should be set for the purpose to ensure the effect of water sealing.
