摘　　要：随着京港澳高速公路交通流量的快速增长,原有基础设施已难以满足当前的交通需求,本文依托京港澳高速公路JGATJ-2标段改扩建工程,围绕“边运营边施工”模式,详细研究了施工期间的交通组织设计,采用了限速、车道封闭和交通分流等策略,对施工期间的防护、交通标志设置进行了具体分析,为降低施工对交通流的影响,保障交通安全和工程进度提供了借鉴和参考。With the rapid growth of traffic flow of Beijing-Hong Kong-Macao expressway,the original infrastructure has been difficult to meet the current traffic demand.Based on the reconstruction and expansion project of JGATJ-2 section of Beijing-Hong Kong-Macao expressway,this paper studies the traffic organizati-on design during the construction period in detail around the mode of"operation while construction",and adopts the strategies of speed limit,lane closure and traffic diversion.The protection and traffic sign setting during the construction period are analyzed in detail,which provides reference for reducing the impact of construction on traffic flow and ensuring traffic safety and project progress.
