枣林互通方案选型研究

The Study on the Type Selection of Zaolin Interchange

山区高速公路受地形、地貌影响,布设较为困难,作为公路节点的互通式立交,在考虑功能、造价、安全的因素下,如何选型就显得非常重要。结合枣林互通的选型过程,研究互通方案选型的方法。根据交通量及地形控制因素,提出多种互通方案进行比选。结合互通功能、造价、安全等因素,确定最优的互通方案,可为类似的工程设计提供参考。

The route design of expressways in mountainous areas is difficult due to influence by topography and landform. The type selection of interchange is of great importance with consideration of function, cost and safety. Combined with the selection process of Zaolin Interchange, this paper studied the selection method of interchange. A variety of schemes for interchange were proposed for comparison and selection according to traffic volume and topographic control factor. The optimum scheme of interchange was confirmed based on interlinked function, cost and safety, which could provide reference for the similar engineering design.
