城市管线综合交叉口竖向设计研究

Study on the vertical design of complex pipeline in urban intersection

利用优化的思想,针对城市管线综合交叉口竖向设计的特点,建立了一个管线综合交叉口竖向设计优化模型;根据土方工程量最小化的原则,将管线综合竖向设计方法进行了程序化设计,使得竖向设计有了在计算机上实现的可能;针对程序模型中的不足,提出了一种定性调整的方法;并运用该模型对西安大明宫地区太华北路与凤城二路交叉口进行了实例设计,得到设计方案,证实了模型的可行性和有效性.

Based on the thought of optimization and considering the features of the vertical design, an optimization model of vertical design for complex pipeline in urban intersection is established. According to the principle of minimizing earthworks, the programmable design about method of vertical design on complex pipeline in intersection is achieved. Then it is possible to do the vertical plan on the computer. In view of the insufficiency of programmable model, a qualitative adjustment method is proposed, and a case design about intersection at Taihua North Road and Fengcheng Road 2 in Xi＇an is carried out with this model. The design plan is obtained to verify the feasibility as well as the effectiveness of the model.
