摘　　要：在保证高速公路改扩建施工进度的前提下,为最大程度降低对改扩建公路及周边区域交通的影响,以高速公路“四改八”工程为例,对改扩建施工期较复杂的互通式立交的交通组织进行了研究。在结合相关标准、规范对高速公路改扩建互通式立交施工期保通要求进行分析的基础上,重点对高速公路互通式立交改扩建施工期分流和保通两种交通组织模式进行了方案研究。分流方案以深圳市某条高速公路改扩建为例进行说明;保通设计研究为便于说明和理解,以单喇叭互通式立交为例,针对不同施工类型的互通式立交施工期的交通组织方案进行分类归纳,重点对互通跨线桥和匝道端部施工时需配套的交通保通设计进行研究。相关思路、具体案例可为国内类似项目的交通组织设计提供经验借鉴和参考。Under the premise of ensuring the construction progress of expressway reconstruction and expansion, in order to minimize the impact on the reconstruction and expansion of highway and surrounding regional traffic, in this paper relying on the widening project of an expressway from 4 lanes to 8 lanes, the traffic organization of complex interchanges during the construction period is studied. Based on the analysis of the traffic control requirements in the construction period combined with the relevant standards and specifications,the paper focuses on the research on two traffic organization modes of diversion and traffic control in the construction period.The diversion scheme is illustrated by taking the reconstruction and expansion of an expressway in Shenzhen as an example;for the convenience of explanation and understanding,the study of unblocked traffic scheme is relied on the single trumpet interchange,the traffic organization schemes of different construction types of interchanges during the construction period are classified and summarized,with the emphasis on the traffic protection design for the construction of interchange overpass and ramp end.It is hoped that the relevant ideas and specific cases in this paper can provide experience and reference for the traffic organization design of similar projects in China.
