摘　　要：利用地形、薄膜、弹性网、有限元数值模型,针对河道地形控制断面的特点提出了地形等值线的有限元仿真方法,其具有概念明确、编制程序简单、绘制的图形更精确等特点,利用该方法确定的河道地形比较自然,比一般插值方法更接近河道的真实情况.另外,还讨论了汊道、垂直陡岩等特殊地形的网格化处理方法.The finite element method of simulating topographical contour proposed to measure the control sections of river terrain is described in this article, and this method have been developed using a number of analogues such as topography, membrane,elastic network and finite element numerical modeling. A grid treatment method used for the characteristic topography of river fork, escarpment, etc. is discussed as well.
