新增互通式立交出入口与既有服务区合并设置研究

Research on Combination of Newly-added Interchange Entrances and Existing Service Areas

互通式立交和服务区均为高速公路沿线的主要构造物,由于两者的服务功能不同通常分开设置。但随着城市建设进程的加快,高速公路开口与地方道路衔接的需求增加,市内高速公路周边土地资源一般较为紧缺,在不影响营运安全的前提下,新增出入口采用互通式立交与服务区合并设置的形式,可以有效节约土地资源、减小工程费用。结合广州南站南出口与金山服务区匝道合并设置的方案,对新增互通式立交出入口和既有服务区合并设置条件和要素以及注意事项进行简要归纳总结。

Interchanges and service areas are the main structures along the expressway.The both are usually set separately because of the different service functions.However,with the acceleration of the urban construction process,the demand for expressway openings to connect with local roads increases.Land resources around expressways in a city are generally in short supply.On the premise of not affecting operational safety,the form of combining interchanges and service areas is adopted for the newly-added interchange entrances,which can effectively save the land resources and reduce the engineering costs.Combined with the research on the scheme of combining the south exit of Guangzhou South Railway Station and the ramp of the Jinshan Service Area,the setting conditions,essentials and attentions in the combination of newly-added interchange entrances and existing service areas are briefly summarized.
