| 摘 要： | 把局部间断伽辽金有限元法(LDG)运用到渗流分析中,编制了LDG法渗流分析的计算程序,运用该程序对均质或非均质渗流场分布进行分析,把所得结果与解析解或一般有限元法所得结果进行比较,证明LDG法在渗流分析中是十分有效的。

| Abstract: | The local discontinuous Galerkin(LDG) finite element method was applied to the analysis of seepage fields.A computer program for the solution of LDG was worked out.The seepage fields of homogeneous or non-homogeneous aquifers were analyzed by use of the computer program.The calculated results were compared with those of analytical solution and general finite element methods.The effectiveness of LDG in the analysis of seepage fields was validated. |
