【摘要】 拱坝是一种重要的坝型，在许多水利枢纽中发挥着重要作用。和其他坝型相比，拱坝具有结构合理、用材最省、稳定性较强等优点。但拱坝作为一种特殊的坝型，其体型结构复杂、受力条件也较复杂，因而计算困难、设计起来相当地耗费时间和精力。如何利用现代的计算机技术，辅助我们进行拱坝设计，使我们从重复繁重的劳动中解放出来，是一项有实际意义的研究课题。 本文从拱坝计算机辅助设计研究的现况出发，首先详述阐述了拱坝体形的分类及其数学模型描述。然后从三大块研究拱坝计算机辅助软件的开发：一、拱坝应力计算部分，采用高斯纯拱法作为应力计算模型，对各类拱坝进行应力计算分析；二、拱坝体形优化部分，采用满应力准则法，非线性约束规划方法对拱坝进行优化；三、自动绘图部分，利用visual basic与AutoCAD链接，采用AutoCAD二次开发技术研究了拱坝的AutoCAD自动绘图。最后对本文所做的工作进行总结，提出今后研发的任务、方向和展望。更多还原

【Abstract】 Arch dam is a very important type of all dams. Being an important component of hydro-junction, it makes use in flood protection, water storage. Compared with dams of other types, arch dam has more rational structure, less material, and stronger stability. But as a special type, it has complex body and has difficulty in structure’s calculation, and it will take more time in design. How to free from strenuous and repeated work and help us in design of arch dam by using technique of computer? Now it becomes an actual and valuable research issue.This paper firstly clarifies the present status of arch dam’s design by computer aided. Then it describes the classification of arch dam and its mathematical model. And then I research the development of CAD (computer aided Design) in arch dam through three parts. First part is calculation of arch dam’s stress, in it Gauss pure arch method will be taken into the model of stress calculation and it can calculate all types of arch dams. Second part is optimization of arch dam’s shape. In it, full stress criterion method and nonlinear programming will be put in use. Third part is Automatic plot of arch dam. In it second development technique of AutoCAD will be put into use in Automatic plot of arch dam. Finally I summarize the all work and shortcoming of this paper, then point out the task, direction and prospect of this research.更多还原
