摘要
论述了人工水幕的应用及原理。以黄岛水封式地下储油洞库的设计方案为模型,通过开挖工况和运行工况的渗流场数值模拟,对人工水幕的水封效果进行了分析评价,表明人工水幕对于稳定地下水位,保证水封条件起到了非常重要的作用。储油洞室渗流量的近似解析解与数值解的一致性,表明采用的近似解析方法和FLAC数值模拟方法合理估算了储油洞室渗流量,其方法是可行的。针对水封式地下储油洞库的渗流场分析和渗流量分析能够为人工水幕的优化设计提供有益的参考。
The application and principles of artificial water curtain are studied. The study model originates from the layout of Huangdao water sealed underground petroleum storage rock caverns. Through simulating seepage field under excavation and operation conditions, the effect of artificial water curtains is studied. It is concluded that the artificial water curtaining is very important for stabilizing underground water table and maintaining hydraulic seal conditions. The agreement between the approximate analytical solution and numerical solution of seepage discharge of storage caverns shows that the approximate analytical method and FLAC numerical method can effectively and reasonably estimate the seepage discharge of storage caverns. The seepage field analysis and seepage discharge analysis for the water sealed underground petroleum storage caverns can provide instructive reference for the optimum design of artificial water curtaining.
