三维非达西渗流的有限元分析

Finite element analysis of three dimensional non-Darcy's seepage flow

本文以非线性渗透规律的两种主要形式为基础,推导并建立了非达西渗流的三维有限元数值记算模型,分析了用有限元法分析非达西渗流的特点,用FORTRAN语言编制了相应的计算程序,并借助堆石坝渗流模型的实测结果进行了验证.

A three dimensional finite element numerical model of non-Darcy's seepage flow is set up, based on two main forms of nonlinear law of seepage flow. The characteristics of finite element analysis in non-Darcy's seepage flow are analysed. The corresponding compute programme in FORTRAN language is coded and checked by the experimental results on model test on rockfill dam, a fair agreement is obtained.
