摘　　要：互通式立交是高速公路重要构造物之一,也是路网中车流转换的重要节点,在设计阶段对互通立交方案进行安全性分析评价是保证后期运营安全的基础。目前国内在进行互通立交安全性评价方面还存在一些不足,这里从互通立交设计中经常存在的问题出发,探讨互通立交安全性评价工作应关注的重点和要点,以期对互通立交设计和评价工作有所帮助。Interchange is one of the most important structures in the highway system;it is also the significant node of traffic conversion in the road network.In the design stage,analyzing and evaluating the safety of the interchange program is the foundation to ensure the security of later operation.At present,there are some deficiencies in interchange safety evaluation in China.Starting from the problems that frequently appear in the process of interchange design,this paper discusses the key points that that we should pay close attention to in interchange safety evaluation,thus making contributions to the design and evaluation of the interchange.
