摘　　要：为解决高速公路同向车道分隔带拆除封闭后的问题,该文结合连霍高速公路郑(州)洛(阳)段大修项目,系统介绍同向车道分隔带的改造方法。通过规范符合性核查、交通运行状况分析、交通事故特征分析和交通安全设施调研等方式,探究同向车道分隔带存在的主要病害及安全隐患,并在此基础上论证同向车道分隔带拆除的可行性。研究结果表明:根据前期调研和分析论证的结果,分别从车道划分、路拱横坡、路径指引系统完善、车道分隔带路面封闭和桥梁封闭等方面提出相应的处治措施,较好地解决了高速公路同向车道分隔带存在的系列问题。In order to solve the problem arising after the demolition and closure of the lane separator in the same direction along the expressway,this paper systematically introduced the reconstruction method of the lane separator in the same direction by studying the overhaul project along Zhengzhou-Luoyang section of Lianyungang‒Khorgos Expressway.The paper explored the main diseases and potential safety hazards existing in the lane separator in the same direction by checking the compliance of specifications,analyzing the traffic operation status,exploring the characteristics of traffic accidents,and investigating the traffic safety facilities.On this basis,it demonstrated the feasibility of demolishing the lane separator in the same direction.According to the results of previous investigation,analysis,and demonstration,the corresponding disposal measures were put forward from the aspects of lane division,crown slope,path guidance system improvement,and road closure and bridge closure with lane separators,which solve a series of problems existing in the lane separator in the same direction along the expressway.
