摘　　要：随着高速公路网不断加密、交通量的持续增长,高速公路主线分岔、合流交通设施不断增多,但目前的相关文献中对主线分岔、合流连接部的研究较少,现行的规范和细则对其规定的条文内容也缺乏实用性。主线分岔、合流连接部控制了高速公路网的整体及局部的运输效率,因此,研究其关键技术指标具有重要意义。本文结合工程案例,分析了主线分岔、合流连接部处车道连续及车道平衡等核心问题,并针对其进行了方案研究。With the continuous densification of the expressway network and the continuous growth of the traffic volume,the traffic facilities for the main line bifurcation and confluence of the expressway are increasing.However,there are few studies on the main line bifurcation and confluence junction in the current literature,and the current specifications and rules are not practical for the provisions.The junction of the main line bifurcation and confluence controls the overall and local transport efficiency of the expressway network,so it is of great significance to study its key technical indicators.Based on a project case,this paper analyzes the core issues such as lane continuity and lane balance at the junction of main line bifurcation and confluence,and conducts a scheme study for them.
