| 摘 要： | 在进行悬臂施工预应力混凝土连续梁桥设计时,绘制预应力钢束施工图纸面临繁杂的钢束数据,人工绘图劳动强度大、效率低、质量也无法得到保证.针对设计过程中面临的以上难题,运用面向对象技术与编程方法建立了布束模块和预应力施工图纸绘制模块.程序是以Auto CAD为平台,利用CAD二次开发工具包Object ARX实现的.

Design of Draw Program of Prestressed Concrete Continuous Beams Built by Cantilever Construction |

| Abstract: | During the design of prestressed concrete continuous beams complicated figures of steel cables have to be dealt with which has brought built by cantilever construction, lots of big troubles for the drawing. Such kinds of drawings often call for high labor intensity while the drawing efficiency is low and the quality of the drawings cannot be guaranteed. To solve the problems above, steel cable distribution module and drawing module have been set up with the object oriented technology and programming method. The whole program is based on Auto CAD and is achieved by Object ARX which is the secondary development kit of CAD. |
