摘要
为了解决有限单元法和有限差分法在模拟条带状水文地质体时可能产生海量数据和耗费大量计算机时的困难,本文提出采用基于区域分解原理的快速自适应组合网格方法FAC法(Fast Adaptive Composite Grid),讨论了FAC法建立和求解地下水模型的基本原理,并将其应用于一个矿山边坡防渗墙体防渗性能的研究。算例采用三层网格建立模型并求解,准确描述出防渗帷幕墙体内部地下水运动的规律,为即将开始的防渗墙设计提供了参考依据。
The fast adaptive composite grid （FAC） method is presented to solve the difficulty of huge data and computing time encountered in the simulation of linear hydrogeologic object such as fault and anti-seepage curtain. FAC method is based on the principle of domain decomposition. In this paper, the basic idea and fundamental algorithm is introduced. Then FAC method with three-level grid technique is applied to a study of anti-seepage curtain embedded in a mine slope. The characteristics of the groundwater flow in the curtain can be depicted in detail. These studies can provide foundation to the coming curtain design.
