摘要
基于地下水热量运移的基本原理 ,本文提出了求解地下水热量运移问题的BEM -FAM耦合法 .该方法原理简单 ,操作方便 ;不仅可以直接计算出地下水流速度 ,而且避免了对流扩散方程数值解中的数值弥散和数值振荡 ,提高了计算精度 .应用本文提出的方法对溪洛渡水电站工程地下水热量运移问题进行了模拟 ,计算结果与地质分析的结论一致 ,表明该方法是可行的 .
According to the principle laws of groundwater thermal transport,the BEM-FAM coupled method is established.With this method the velocity of the groundwater flow can be obtained directly.At the same time,the numerical dispersion and oscillation during solving the convection and diffusion equation are eliminated and accuracy is elevated.The method is applied to the simulation of the groundwater thermal transport in Xiluodu Hydro Project.The calculation result is in good agreement with the analysis of geologist.
