摘要
将 PG(Petrov- Galerkin)有限元方法用于求解饱和渗流问题 ,导出了数值表达式 ,并且对实际问题进行了模拟计算。计算表明 ,采用该方法计算结果精确 ,是收敛和稳定的 ,可以用于饱和渗流问题的求解。
The Petrov Galerkin finite element method is applied to solve seepage flow problem.Anumerical expression has been derived and calculation has been made for the two dimensional earth dam seepage flow problem.The calculated result shows that this method has good accuracy convergency and stability.
