摘 要

近20多年来，计算机软件技术在我国道路基础设施建设中得到了广泛的应用，它改进了我国公路交通和城市交通落后的设计手段。道路计算机辅助工程的出现，对于加快工程测设进度，提高工程质量，经济效益，节约投资，节省人力，减轻劳动强度，以及在实现我国道路建设现代化，满足交通基础设施建设大力发展的要求等方面，有着重大的实际意义。

柯袍线和镜水路都位于浙江省绍兴市柯桥区，两条路相交的位置北邻杭甬运河，南邻宁杭高铁，现在需要在柯袍线和镜水路之间建立立交，保证两条线路的互通。本项目在已有地形图的情况下，在CAD软件中设计互通立交的平面线位，并且在已有的地形图中进行平纵横的组合设计，将设计的各项数据进行汇总后结合各项影响因素进行三种方案的比选，最后对推荐方案进行优化和三维建模。在立交设计的过程中需要用到DPX软件，DPX软件是一款强大的立交设计辅助绘图工具。在它的帮助下，立交设计变得更加高效，准确，从而，可以将更多的时间花在思考如何让设计更合理，实用，美观上。本项目的关键就在于不仅要熟练地掌握CAD,DPX等绘图软件，还要在实际的工程背景下思考，最终做出最符合工程实际的设计。

Abstract

Past 20 years, computer software has been widely used in China's infrastructure construction of roads, which improved China's road transport and urban transport backward design tools. Computer-aided engineering of roads, for survey and design engineering to accelerate progress, improve project quality, economic efficiency, save and invest, save manpower, reduce labor intensity, and the realization of China's modernization road construction, to meet the requirements of transportation infrastructure to develop other aspects of It has great practical significance.

The G329 freeway and JinShui highway are both located in KeQiao District, ShaoXing City, ZheJiang Province. The place two roads intersect are located in south of Hangyong canal and north of Nanjing Hangzhou high-speed rail. Now, it is time to establish interchange between the two way, so as to ensure the intercommunication between the two lines. In this project, the plane position of interchange is designed in CAD software with the existing topographic map, and in the existing topographic map, we should perform plane ,vertical section and cross section design.With the help of design data collected, combined with various factors，we compare the three options. Finally, the recommendation scheme should be optimized and 3D model can be built. In the process of interchange design, we need to use DPX software, and DPX software is a powerful auxiliary design tool for interchange design. With its help, the interchange design becomes more efficient and accurate, so we can spend more time thinking about how to make the design more reasonable, practical and beautiful. The key of this project is not only to master CAD, DPX and other graphics software, but also to consider in the actual engineering background, and ultimately to make the most consistent with the actual design of the project.
