铁路地道桥微机CAD系统的研究与设计

A Personal Computer Aided Drafting System for Highway-Railway Grade Crossing Climination

用于铁路地道桥辅助设计的微机CAD系统,可以对力学计算结果进行数据检索与处理,建立图形库,辅助配筋和自动绘制钢筋混凝土框架配筋图.同时介绍了该软件系统的设计构思,主要程序的设计方法和制图质量控制等技术问题.

A personal computer-aided drafting system is developed for designing highway-railway grade seperation structures. It can process data obtained by mechanical computation, found figure base, distribute reinforcement interactively, and make the drawing of distributed steel bars in reinforced concrete frame. This artide introduces the main essentials about the system, such as the strategy, the principle programs, and the means of design and drawing quality control, etc.
