参数化绘图在渡槽结构优化设计中的应用

Application of parametric drawing to the optimal design for the aqueduct

在大型预应力U型渡槽结构优化设计中,需要将优化设计结果实现自动化绘图. 为解决这一问题,提出了将高级程序语言与AutoLISP相结合以实现参数化绘图的方法,开发了FORTRAN与AutoLISP混合编程程序设计系统.并将此程序设计系统运用于大型预应力U型渡槽槽身断面的优化设计过程中,把优化设计结果方便地转变成了形象直观的图形(文件),从而实现了自动化绘图.

In the process of the optimal design for the large-scale prestressed concrete U-sectioned aqueduct,the optimal results need to be drawn automatically.Therefore,a new method is presented in this paper to realize parametric drawing by combining advanced programming language and Auto LISP,and a mixed language programming design system of FORTRAN and Auto LISP are developed.The programming system are applied to the optimal design of the cross-section of the large-scale prestressed concrete U-sectioned aqueduct,and the optimal results are turned to visual and direct graph conveniently,so automatic drawings are realized.
