【摘要】：高速公路作为我国重要的社会基础设施,在运输能力、通行速度以及安全性能等方面具有突出的优势。而互通式立体交叉目前已成为高等级公路和交通繁重的城市道路不可或缺的重要组成部分。伴随社会经济的发展、区域路网的完善和交通流量的增长,互通式立交作为高等级公路交通转换的枢纽,其担负的交通流量正日益增大,交通方式组成也发生了重大的变化,对互通改扩建施工作业区交通组织相关技术进行研究成为必然的趋势。本论文首先总结了国内外学者关于互通改扩建施工作业区交通组织理论以及安全保障措施的研究现状,确定主要内容是针对高速公路互通式立交改扩建交通组织进行了深入研究。接着,对高速公路互通式立交改扩建的交通组织影响因素进行了详细分析。分析表明：互通作业区与正常通行道路存在不同的交通特性,往往使得互通作业区交通流量重新分布以及产生交通流瓶颈效应。然后,基于交通组织的网络性、协调性和复杂性,深入研究了单喇叭互通立交改扩建为双喇叭互通立交这种形式的施工期交通组织方案设计和交通组织优化设计。最后,结合醴陵东互通改扩建项目,进行交通组织方案设计和交通组织优化设计。对互通式立交改扩建进行相关的交通组织研究,将很大程度上提升我国互通系统施工期间的通行能力和服务水平,同时为我国今后的互通式立交改扩建工程积累宝贵的经验和教训。
[Abstract]:As an important social infrastructure in China, expressway has outstanding advantages in transportation capacity, speed and safety performance. At present, interchange has become an indispensable part of high-grade highways and heavy traffic urban roads. With the development of society and economy, the improvement of regional road network and the increase of traffic flow, as the hub of high-grade highway traffic transformation, the traffic volume of interchange is increasing day by day, and the composition of traffic mode has also changed greatly. It is an inevitable trend to study the related technology of traffic organization in the construction area of interworking reconstruction and extension. Firstly, this paper summarizes the research status of traffic organization theory and safety measures in the construction area of interworking, reconstruction, extension and construction at home and abroad. The main content is to study the traffic organization of expressway interchange. Then, the influence factors of traffic organization of expressway interchange are analyzed in detail. The analysis shows that there are different traffic characteristics between the interworking operation area and the normal road, which often lead to the redistribution of traffic flow and the bottleneck effect of traffic flow in the interworking operation area. Then, based on the network, coordination and complexity of traffic organization, the traffic organization scheme design and traffic organization optimization design during construction period are deeply studied. Finally, combined with Liling East Interchange extension project, traffic organization scheme design and traffic organization optimization design. The study on the traffic organization related to the reconstruction and extension of the interchange will greatly enhance the capacity and service level of the interworking system during the construction period in our country. At the same time, it accumulates valuable experience and lessons for our country's future interchange reconstruction and extension project.
