不规则三角网（TIN）可以高精度的对地形进行表达；除足够密度的离散点外，特征线也是影响TIN模型精度的重要因素。本文讨论了特征线的几种形式及带特征线的TIN模型的构建方法。利用EPS2008软件，分析讨论了该模型在土方计算、纵横断面生成、等高线生成中的应用；结果表明，该模型能有效提高成果精度及生产效率。

The TIN can express terrain with high precision. The feature line is also an important factor affected the accuracy of the TIN model, in addition to sufficient density of discrete points. The paper discusses the construction meth- od of several forms of feature line and TIN with feature line. Using EPS 2008 software, the application of the model is an- alysed in the earthwork calculation, vertical and horizontal cross-section generation and contour generation. The result shows that the model can effectively improve the accuracy of Achievements and efficiency of production, it has a high val- ue of application.
