互通式立交设计中,连接部高程数据图的设计比较繁琐,以往是将其作为交叉口进行平面、立面设计,再在Auto CAD环境下进行图形处理,绘制图形。近年来,本校结合工程实际,对其进行了进一步研究。提出将高程数据图分为四种类型,并编制相应的计算机程序,通过程序运行生成图形接口文件,在Auto CAD环境下生成图形,节省了大量的人工,获得了较为满意的效果。本文着重介绍设计方法及程序的功能与使用。
In the design of interchange, the design of the elevation data of the connection is complicated. In the past, it was designed as a plane and elevation design at the intersection, and then the graphics were processed and drawn in the Auto CAD environment. In recent years, our school has carried on the further research to it with the engineering practice. The paper divides the elevation data into four types and compiles the corresponding computer programs. Through the program running, it creates the graphic interface file and generates the graphics in the Auto CAD environment, which saves a lot of labor and achieves satisfactory results. This article focuses on the design methodology and procedures of the function and use.
