摘要
随着高速路网的日渐完善,城市环线及快速通道支线建设项目日渐增多,当新增互通立交与已建互通立交之间的距离难以满足规范所要求的净距时,利用既有互通组合形成复合式互通成为立交建设的重要课题之一。以丙村复合式互通立交设计为例,通过方案比选,递进式地梳理了复合式互通立交设计的要点及难点,总结并提出了各向交通转换优先、因地制宜,充分利用原互通结构,以降低造价的设计原则,并提出利用主流匝道与高速公路构建立交总体架构的设计思路和方法。
With the improvement of highway network, projects for city ring road and city expressway have increased.Making full use of existing interchange to form compound interchange has become an important subject on interchange construction.In this paper, taking the design of compound interchange in Bingcun as an example, the design ideas of an overall interchange combining mainstream ramp with expressway have been put forward, which could provide reference for similar projects.
