深圳市坂银通道南坪立交改扩建方案研究

Study on Reconstruction and Extension Scheme of Shenzhen Banyin Expressway Nanping Interchange

城市现有路网的不断改善依赖于不断完善道路建设,路网节点改扩建的成功与否更是直接影响路网功能发挥的重中之重。以深圳市坂银通道工程南坪立交为例,介绍了该立交在改扩建设计过程中,对规范指标选用、立交方案设计、水土保持措施以及交通保通设计等问题的处理思路,有关经验可供相关专业人员参考。

The continuous improvement of the existing urban road network is dependent on the continuous perfection of road construction. The success of the road network node reconstruction and extension is a direct impact on the function of road network. Taking Shenzhen Banyin Expressway Nanping Interchange as an example, the article introduces the ideas of the specification index selection, the interchange scheme design, the water and soil conservation measures, and the traffic insurance design in the reconstruction and extension design of this interchange. The relative experience can be referenced for the similar projects.
