【摘要】 提出了一种渗流分析的固定网格法──虚单元法，该法通过迭代可较准确地求出自由面边界，计算区域逐步逼近实际渗流区域，可应用于稳定和非稳定渗流计算。更多还原

【Abstract】 A fixed mesh method or the imaginary elements method for solving seepage flow analysis is presented in this paper.The free surface bound can be calculated precisely through alternate and the calculative region can approach the actual seepage flow region.The method can be used for steady and unsteady seepage flow calculation.更多还原
