摘　　要：随着我国各地经济的快速发展,高速公路的新建与改扩建项目增多。出入高速公路的节点及高速之间的交叉相对增加,同时交通运输部对互通立交规范及细则不断完善。结合狮子洋通道工程项目中的设计实践内容,对施工图设计时需处理的匝道汇流细节设计进行归纳与总结,为互通匝道合流连接部设计提供参考。With the rapid economic growth witnessed across different regions in China,there has been a surge in the construction,renovation,and expansion projects of expressways.Consequently,there has been a relative increase in the number of entry and exit points on expressways,as well as intersections between them.Simultaneously,the Ministry of Transport has been consistently enhancing the standards and particulars pertaining to interchanges.In the paper,relying on the design practice in the Shiziyang Channel project,the detailed design of ramp confluence that needs to be dealt with in detailed engineering design is summarized and concluded to provide reference for the design of ramp confluence connection.
