立交孪生设计方法应用研究

互通立交设计需要设计人员具有大量的设计经验和知识储备，同时互通立交设计工作量极大。通过介绍一种基于匝道平面图形模板的立交孪生自动化设计方法，快速完成两条主路交叉下的立交布线工作。结合基于此方法开发的辅助设计软件，实现立交平面自动定线功能，验证了该方法的合理性与可操作性。

Study on Application of Interchange Twin Design Method

The design of interchange requires the designers to have the abundant experience and knowledge reserves. At the same time, the design workload of interchange is enormous. An automatic design method of interchange twin based on the ramp plane graphic template is introduced to quickly complete the interchange layout under the intersection of two main roads. Combined with the assisting design software developed by this method, the automatic layout function of interchange plane is realized. The rationality and operability of this method are verified.
