摘　　要：有限单元法广泛应用于土木建筑、岩土工程、地铁隧道和水利工程等各个领域。基于此,介绍了平面有限单元网格自动生成原理,指出该原理存在两个缺陷,并提出改进方法。此外,阐述了如何在AutoCAD环境利用C#开发平面有限单元自动生成程序,描述了程序实现的关键步骤和使用方法,同时,应用一个实例验证程序的正确性,并提供程序的应用效果。The finite element method (FEM) is widely used in civil engineering, geotechnical engineering, metro tunnel and hydraulic engineering. Based on this, the principle of automatic generation of planar finite element meshes is introduced. Two defects of the principle are pointed out, and an improved method is proposed. In addition, how to use C# to develop the automatic generating program of planar finite element in AutoCAD environment is described. The key steps and the method of using the program are described. At the same time, one examples are used to verify the correctness of the program and to provide the application effect of the program.
