互通立交改扩建设计方案比选

Comparison and Selection of Interchange Reconstruction and Expansion Design Scheme

随着高速公路网的逐步完善和交通量的快速增长,通过改建既有互通立交从而实现新建高速公路和现有路网的交通转换将成为一种趋势。以阳曲大盂至盂县六岭关高速公路起点互通立交改造设计为例,对单喇叭互通改造为枢纽互通立交进行方案研究与比选,对今后的设计有一定的指导意义与参考价值。

With the gradual improvement of expressway network and the rapid growth of traffic volume,it will be a trend to realize the traffic conversion between the new expressway and existing expressway network by the reconstruction and expansion of the existing interchange.This paper studies and compares the schemes transforming single-trumpet interchange into hub interchange based on the interchange at the starting point of Dayu to Liulingguan Expressway,which can provide certain guidance and reference for the design in the future.
