摘要
介绍岩土工程数值分析中常用的无限单元的坐标变换式和位移函数,并对一具有精确解的平面问题进行常规有限元分析及有限元与无限元耦合分析。研究表明,引入无限元分析无限域或半无限域问题具有更高的精确性,且节省计算工作量。
In this paper, the coordinate transformation format and displacement function of infinite element which is in common use in numerical analysis of geotechnical engineering is introduced, an plane problem which has exact solution is analysed with general method of finite element and coupling method of fininte-infinite element. It is derived that the coupling analysis method for the problem of infinite region or half infinite region has the advantage of more satisfactory precision and less workload of computation.
