摘　　要：随着高速公路事业的飞速发展,互通式立交也大量出现。目前针对互通式立交设计方面存在的问题主要包括三个方面:立交加减速车道长度、立交间距问题、立交匝道线形质量等。主要从这三个方面进行了国内外研究现状的文献综述,并根据目前立交设计的情况指出了存在的问题与缺陷,为进一步优化立交设计,保证行车安全顺畅提供了有力依据。With the rapid development of highway, there are lots of the interchanges. At present, there are problems in the design of interchange, including three aspects ： the length of the acceleration and deceleration lane, the distance between the interchanges, the quality of interchange ramp＇ s alignment and so on. This paper mainly from the three aspects performed the literature review of the research status at home and abroad, and the problems and defects are pointed out according to the current situation of interchange design in order to further optimize the design of interchange, to ensure traffic safety and smoothly.
