摘　　要：随着城市化进程不断推进,城镇规划已逐渐向城郊区域的高速公路递进,与高速公路相交的道路须进行市政化改造以满足规划区的发展。同时,伴随高速公路交通量的逐年增长,高速公路改扩建势在必行,但城郊区的互通改建存在较多控制因素,在满足交通转换服务水平的前提下,还须考虑城市景观融合、周边地块发展等因素。以G98环岛高速公路仙沟互通立交改扩建设计为例,结合各影响因素对互通方案进行比选,为今后城郊互通改建提供参考思路。With the continuous expansion of the city,the urban planning has gradually advanced to the expressways in the suburban areas.The roads intersecting with the expressways need to be reconstructed into municipal roads to meet the development of the planned areas.Meanwhile,with the annual increase in the traffic volume of the expressways,the reconstruction and expansion of the expressways are imperative.There are many control factors in the reconstruction of the interchanges in the suburban areas.On the premise of meeting the traffic conversion service level,factors such as the integration of the urban landscape and the development of the surrounding plots also need to be considered.Taking the reconstruction and expansion design of the Xiangu Interchange on the G98 Ring-Island Expressway as an example,this paper compares and selects the interchange schemes in combination with various influencing factors,providing a reference for the reconstruction of the suburban interchanges in the future.
