摘　　要：分析了干线公路快速化改造提出的背景和快速干线公路的技术要求。在干线公路现状调研的基础上,提出了影响干线公路快速化的主要问题是行车的纵、横向干扰,并从道路断面改造方式,交叉改造方式,平交控制间距等方面提出了干线公路快速化改造可采用的技术解决方案。This paper analyzed the background of rapid reconstruction and technical requirements of trunk highway. Based on the study of the＇ present situation of trunk highway, it was proved that the major effecting factors of trunk highway rapid reconstruction is vehicle longitudinal and transverse interference. In addition, the technical solutions were proposed from the different aspects such as reconstructions of cross section, interchange and grade crossing.
