摘要
互通立体交叉是路网系统中的重要节点,担负公路之间交通流转换的重要功能。文中以沪陕高速公路新增枣林湾互通立交为工程实例,通过现场调查和资料收集,分析区域路网、交通量预测、沿线自然地理条件等控制因素,选定互通立交合适位置。在确定合适选址后,细化互通立交设计方案并进行比选,推荐最优互通立交方案。
Interchange is an important node in the network system,which takes on the important function of highway traffic flow conversion. Taken the new interchange of Shanghai-Shaanxi highway as an example, through field investigation and data collection, the control factors such as regional road network, traffic volume forecast and natural geographical conditions of the road are analyzed. An appropriate location for the interchange is selected. After determining the appropriate site selection, this paper proposes an optimal interchange scheme is determined from comparison of the design scheme of the interchange.
