摘　　要：针对大坝采用有限元分析单一软件建模时操作繁琐复杂、效率低等不足,基于AutoCAD、HyperMesh和MSC.Marc软件的各自特点,提出了综合应用三种软件的优势完成有限元分析过程的方法。实例结果表明,该方法可使有限元分析过程清晰明了、操作简捷流畅、参数设置方便、出错易控制和修改,大幅提高了大坝有限元分析的精度和效率。Aiming at the problem of operation redundancy, process complexity and low efficiency in the finite element analysis of dam, caused by use single software to complete the whole process of finite element analysis, the AutoCAD, HyperMesh and MSC. Marc softwares are applied synthetically to complete the pre-processing, solving and post-processing of the whole finite ele- ment analysis process based on their respective features. The example shows that the integrated use of three types of software can raise the clarity of the calaulation, take brief and smooth operation, make the parameters setting more convenient, easy to control and amend the mistakes. This method greatly improve the analysis efficiency.
