京港澳高速公路改扩建工程保通方案研究

Study on the Traffic Organization Project of JingGang'Ao Freeway Reconstruction

介绍了京港澳高速公路交通现状,选取国内典型高速公路改扩建工程指标、建设条件和施工方式等因素进行对比分析,提出施工期相应的保通方案,讨论了各保通方案的特点;结合京港澳高速公路改扩建工程规模及实际,分析了各保通方案的适宜性,得出了京港澳高速改扩建保通方案。

Firstly,the paper introduced the current traffic situation of Jinggang＇ao freeway, performed a comparative analysis of engineering index, construction condition and application methods among do- mestic typical freeway reconstruction project, put forward corresponding unobstructed traffic schemes and discussed the features of each scheme. Finally, combining engineering scale and practice of recon- struction project of Jinggang＇ao freeway, the paper analyzed the suitability of each unobstructed traffic scheme, and come to the conclusion of final scheme.
