城市道路与干线公路平交口差异化协调设计

Differentiated Coordination Design of Grade Intersection of Urban Road and Trunk Highway

摘要:

普通干线公路和城市道路由于技术标准体系和管理模式的不同，决定了各自在功能定位、构造和设计方法上均有较大差异。针对现状干线公路与城市道路平面交叉口存在的问题和原因，分析干线公路和城市道路平交口衔接要素的差异性，并从城市道路与干线公路平面交叉口差异化协调设计方面提出合理可行的设计方法，以期能够为类似工程实践提供设计参考。

Abstract:

Because of the different technical standard systems and management modes, there are the great differences in the functional orientation, construction and design method between ordinary trunk highway and urban road. Aiming at the problems and causes existing in the grade intersection of trunk highway and urban road now, the differentiation of connection elements at the grade intersection of trunk highway and urban road is analyzed. The reasonable and feasible design method is proposed from the differentiated coordination design of grade intersection of urban road and trunk highway in order to provide the design reference for the practice of the similar projects.
