摘　　要：近年来,高速公路改扩建项目不断增多,投资不断加大。介绍了高速公路改扩建设计原则,并以某互通式立交设计为例,提出了主线平纵面设计方法、进行互通式立交方案比选。研究表明,高速公路改扩建项目互通式立交设计过程中,需要结合交通量主要方向、车流交织情况、用地规模、现有构造物利用情况、工程造价、施工组织方案等因素进行综合比选,确定推荐方案。In recent years,with the growing of expressway reconstruction and extension projects,the investment continues to increase.In the paper,the design principles of expressway reconstruction and extension are introduced,and taking one interchange as the background,the design method of plan and profile and interchange design alternatives are proposed.The conclusion indicates that,in interchange design process of expressway reconstruction and extension project,comprehensive comparisons of design alternatives should be carried out according to mainstream direction of transportation,interweaving of traffic flow,land occupation scale,utilization conditions of existing structures,project investment and construction organization plan so as to determine the preferred design scheme.
