拱坝三维设计技术应用与研究

Application and Research of Arch Dam 3-D Design Technology

基于CATIA三维设计软件平台,对双曲拱坝模型三维设计进行研究,根据双曲拱坝的设计思路,提炼拱坝设计的关键参数,提出了拱坝三维设计的工作思路和实现方式。以CATIA知识工程和参数化设计为基础,建立起拱坝三维模型及参数间的约束关系,将设计规范和设计经验嵌入三维设计过程,实现拱坝参数化三维设计。

Based on 3-D design software CATIA, we studied on the design method of double curvature arch dam. According to the design process of the double curvature arch dam, some key design parameters had been elected and established. Also we set up the constraint relation between the 3-D model and the parameter of double curvature arch dam based on the project of parametric design in CATIA, realized 3-D parametric design of double curvature arch dam through the 3-D process that combined relevant design specifications with experiences of design.
