黎城枢纽互通方案选型设计

Selection and Design of Licheng Hub Interchange Schemes

以山西省黎城—陵川夺火高速公路黎城枢纽互通方案选型为例,介绍在复杂路网及多因素控制条件下,枢纽互通立交改造方案设计应综合考虑交通量、主线平纵面指标、既有工程,以及沿线土地利用情况。根据拟建项目特点及黎城枢纽节点功能,提出经济、合理的最优方案,可供类似互通方案的布设参考。

Focusing on the selection design for the hub interchange schemes of the Licheng-Lingchuan Duohuo Expressway in Shanxi Province,this paper introduces that under complex road network and multi-factor control conditions,the design of hub interchange transformation schemes should comprehensively consider the traffic volumes,mainline vertical and horizontal indicators,existing engineering,and land use along the route.According to the characteristics of the proposed project and functions of Licheng Hub,the optimum economical,and reasonable scheme was put forward,providing a reference for the design of similar interchange schemes.
