摘　　要：由于水工建筑物的形体及地形条件复杂,建立有限元模型的范围又大,直接用MARC等其他结构分析软件来建立三维有限元模型往往难度很大,而AutoCAD具有非常强大的平面建模功能则弥补了这一不足。为此,以复杂岔管来划分网格为例,论述如何导入AutoCAD中建立的平面模型,并在Hyper-Mesh中剖分为三维有限元模型和在MARC中的计算。Due to the complexity of the hydraulic structure, land configuration and the large range of FEM, it is difficult to build 3D finite element model with the structure analysis software such as MARC, but AutoCAD has a strong function of building plain model. Taking the building grid of complex branch pipe for example, the paper introduces how to lead in the plain model in the form of AutoCAD to HyperMesh, and how to build 3D FEM with HyperMesh and to calculate with MARC.
