拱坝CAD系统的研制,是水利水电规划设计管理局下达给中南院的重点攻关项目。本片详细阐述了拱坝CAD系统研制的必要性及研制的主要过程。片中以东江工程为例,介绍了地形、地质参数输入、多心圆拱体型设计,分载法应力计算、稳定分析、前后处理程序与拱坝设计参考资料信息库等程序的使用。拱坝CAD系统的研制成功,大大减轻了设计人员的劳动强度;对缩短设计周期,提高设计质量作出了很大的贡献。
The development of arch dam CAD system is a key research project issued by Central Water Resources and Hydropower Planning and Design Bureau to Central South Hospital. The film elaborates the necessity of the development of arch dam CAD system and the main process of development. Taking Dongjiang Project as an example, this paper introduces the use of topography, input of geologic parameters, multi-center arched design, stress calculation of sub-load method, stability analysis, pre-postprocessing program and arch dam design reference database. The successful development of arch dam CAD system has greatly reduced the labor intensity of designers and made a great contribution to shortening the design cycle and improving the design quality.
