摘要
随着高速公路网的不断加密以及交通需求的日益增长,小间距互通式立交逐渐增多。如何保证小间距互通式立交的运行安全已成为业界倍受关注的问题。阐述了小间距互通式立交的概念及其应用,分析了小间距互通式立交的运行特点,并针对不同间距的小间距互通式立交,分别给出了相应的设计方法及安全保障措施,供同行交流探讨。
With the increasingly intensiveexpressway network and growing transportation demand, application of small spacing interchangeincreased gradually. How to ensure the safety operation of the small spacing interchange has become the focus problems of the industry. This paper presented the concept and application of small spacing interchange and analyzed the operation feature of small spacing interchange. Focused on small spacing interchanges of different spacings, it also provided corresponding design method and safety precautions for peer discussion within the industry.
