【摘要】：高速公路作為我國重要的社會基礎(chǔ)設(shè)施,在運輸能力、通行速度以及安全性能等方面具有突出的優(yōu)勢。而互通式立體交叉目前已成為高等級公路和交通繁重的城市道路不可或缺的重要組成部分。伴隨社會經(jīng)濟的發(fā)展、區(qū)域路網(wǎng)的完善和交通流量的增長,互通式立交作為高等級公路交通轉(zhuǎn)換的樞紐,其擔(dān)負的交通流量正日益增大,交通方式組成也發(fā)生了重大的變化,對互通改擴建施工作業(yè)區(qū)交通組織相關(guān)技術(shù)進行研究成為必然的趨勢。本論文首先總結(jié)了國內(nèi)外學(xué)者關(guān)于互通改擴建施工作業(yè)區(qū)交通組織理論以及安全保障措施的研究現(xiàn)狀,確定主要內(nèi)容是針對高速公路互通式立交改擴建交通組織進行了深入研究。接著,對高速公路互通式立交改擴建的交通組織影響因素進行了詳細分析。分析表明：互通作業(yè)區(qū)與正常通行道路存在不同的交通特性,往往使得互通作業(yè)區(qū)交通流量重新分布以及產(chǎn)生交通流瓶頸效應(yīng)。然后,基于交通組織的網(wǎng)絡(luò)性、協(xié)調(diào)性和復(fù)雜性,深入研究了單喇叭互通立交改擴建為雙喇叭互通立交這種形式的施工期交通組織方案設(shè)計和交通組織優(yōu)化設(shè)計。最后,結(jié)合醴陵東互通改擴建項目,進行交通組織方案設(shè)計和交通組織優(yōu)化設(shè)計。對互通式立交改擴建進行相關(guān)的交通組織研究,將很大程度上提升我國互通系統(tǒng)施工期間的通行能力和服務(wù)水平,同時為我國今后的互通式立交改擴建工程積累寶貴的經(jīng)驗和教訓(xùn)。
[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.
