Solving methods of groundwater model with fast adaptive composite grids

摘要: 本文针对当前地下水模型中包括断裂、防渗帷幕在内的线形水文地质对象(L ineStyle Hydrogeological Ob ject)的模拟难点,研究基于重叠型区域分解原理的快速自适应组合网格方法(Fast Adaptive Composite G rid—FAC)。论文首先概括当前线形水文地质对象的模拟手段及其存在的不足,进而讨论FAC方法建立和求解地下水模型的基本原理。通过对理想的地下水流模型的求解,表明该方法能够满足线形水文地质对象的精细模拟求解的要求,且求解效率较高。

Abstract: In order to overcome the difficulty in simulating the Line Style Hydrogeological Object such as rupture and seepage proof curtain,this paper proposes using the FAC(Fast Adaptive Composite Grid) method,which is based on the overlapping domain decomposition method,to build and calculate the groundwater simulation with LineStyle Hydrological Objects.In this paper,the methods for simulate the linestyle objects and shortages of the methods are summed up firstly,and the fundamental algorithm is introd...
