摘　　要：由于城市化进程的加快以及交通量的日益增加,所以国内许多高速公路及城市快速路面临车道拓宽及新增出入口的改造问题。以江珠高速新增六乡互通项目为例,以交通量预测分析为基础,确定匝道车道数、收费站规模以及建设时序等关键要素;并结合国土空间规划及现状用地条件,避让永久基本农田及高压廊道,降低工程总体用地规模,采用单喇叭互通的平面线形方案;分析了互通总体设计中的主要控制因素。详细论述高速公路改扩建对单喇叭互通立交设计的影响,为其他类似高速公路改扩建单喇叭互通立交的总体设计提供借鉴和参考。Due to the acceleration of urbanization and the increasing traffic volume,many domestic expressways and urban expressways are facing the problems of lane widening and new entrance&exit reconstruction.Taking the newly-added Liuxiang Interchange Project of Jiangzhu Expressway as an example,based on the traffic volume forecast analysis,determine the number of ramp lanes,toll station scale and construction timing and other key factors;in combination with the land space planning and the current land use conditions,avoid permanent basic farmland and high-voltage corridors,reduce the overall land use scale of the project,and adopt the plane alignment scheme of single-horn interconnection.The main control factors in the overall design of interconnection are analyzed.The influence of expressway reconstruction and expansion on the design of single-horn interchanges is discussed in detail,which provides reference for the overall design of other similar expressway reconstruction and expansion singlehorn interchanges.
