摘要
应用FEPG软件自动生成渗流计算程序,并将该程序应用于三维渗流场分析中.在稳定渗流计算时,采用死活节点法迭代求解自由面,并对该方法进行了改进;在饱和-非饱和渗流计算时,对计算参数加以适当的处理,采用合适的时间差分格式求解方程.算例表明,将FEPG应用于渗流分析是可行的.
The seepage computation program, which is automatically generated by FEPG software, is used in 3D seepage field analysis. In steady seepage analysis, the free surface is obtained from integrative calculation of the improved live and dead node method. Based on the appropriate processing of parameters, the equation is solved by a suitable finite difference scheme for saturated-unsaturated seepage analysis. Some examples show that FEPG is applicable to seepage analysis.
