The Development And Research Of Software For Computer Aided Design On Arch Dam

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.
