【摘要】：隨著我國社會(huì)經(jīng)濟(jì)的快速發(fā)展,各省域、市域路網(wǎng)規(guī)模逐漸擴(kuò)大、密度不斷提高、通達(dá)深度進(jìn)一步改善,然而在長(zhǎng)期的重負(fù)荷交通作用下,部分公路開始進(jìn)入大修階段,這些公路已經(jīng)在路網(wǎng)中占據(jù)重要功能,一旦因施工導(dǎo)致道路通行能力大幅度降低甚至交通中斷時(shí),會(huì)對(duì)正常的路網(wǎng)交通運(yùn)行產(chǎn)生破壞,引起交通擁擠、堵塞,甚至導(dǎo)致交通事故,不僅降低了道路交通運(yùn)輸效率,還會(huì)造成嚴(yán)重的交通安全問題。繞城高速公路是隨著城市發(fā)展需求而出現(xiàn)的城市高速公路,發(fā)展時(shí)間不長(zhǎng),但是近幾年隨著繞城高速公路發(fā)展到了一定的階段,為維持其服務(wù)水平,供城市交通及過境交通通行,繞城高速公路開始進(jìn)入大修期,然而因繞城高速具有極其重要交通功能,承擔(dān)著繁重的交通量,大修施工會(huì)對(duì)區(qū)域高速路網(wǎng)以及城市的快速路網(wǎng)會(huì)產(chǎn)生更大的影響,為最大限度的降低施工與通行交通的相互干擾,保障繞城高速隧道大修施工期間路網(wǎng)交通安全暢通,對(duì)繞城高速隧道大修施工期間的交通組織研究勢(shì)在必行。首先,本文針對(duì)繞城高速隧道的特性進(jìn)行分析,包括繞城高速特性、繞城高速隧道結(jié)構(gòu)特性和施工影響下的隧道交通特性等幾個(gè)方面,同時(shí)參考高速公路路段大修施工技術(shù)確定繞城高速隧道的大修施工方案,并根據(jù)不同施工方案下的占道方案設(shè)計(jì)隧道施工區(qū)交通組織方案,分析不同交通組織方案的優(yōu)缺點(diǎn)及適用情況。然后,通過關(guān)鍵影響因素選取,分析大修施工的直接、間接影響范圍和強(qiáng)度,同時(shí)根據(jù)不同的隧道大修施工方案特性,分析研究出施工區(qū)以及外圍不同的交通組織策略和相配套的交通管理性設(shè)施,形成一套完備的繞城高速隧道大修施工交通組織方案;并結(jié)合城市交通的特點(diǎn),選取合適的評(píng)價(jià)方法及部分關(guān)鍵性指標(biāo)對(duì)繞城高速隧道大修施工交通組織方案進(jìn)行評(píng)價(jià),判斷交通組織方案的可行性以及實(shí)施效果,為方案改善提供依據(jù),同時(shí)也降低了方案實(shí)施的風(fēng)險(xiǎn),使交通組織方案的實(shí)施效用最大化。最后,結(jié)合杭州繞城高速黃鶴山隧道大修施工,設(shè)計(jì)隧道施工方案,以及隧道施工期間的施工區(qū)及外圍交通組織方案,對(duì)繞城高速隧道大修施工的交通分流組織方案進(jìn)行了實(shí)證分析,并根據(jù)確定的繞城高速隧道施工交通組織方案評(píng)價(jià)指標(biāo),對(duì)隧道大修施工交通組織方案進(jìn)行評(píng)價(jià)分析,最終形成完備的繞城高速隧道大修施工交通組織方案,實(shí)施效果良好。
[Abstract]:With the rapid development of China's social economy, the scale of provincial and municipal road network is gradually expanding, the density is increasing, and the depth of access is further improved. However, under the effect of long-term heavy traffic, some highways begin to enter the stage of overhaul. These highways have occupied an important function in the road network. Once the road capacity is greatly reduced or even the traffic is interrupted due to the construction, it will destroy the normal road network traffic operation and cause traffic congestion and jam. Even lead to traffic accidents, not only reduce the efficiency of road traffic transportation, but also cause serious traffic safety problems. The highway around the city is a kind of city highway which appears with the demand of the city development. The development time is not long. But in recent years, with the development of the highway around the city to a certain stage, in order to maintain its service level, For urban traffic and transit traffic, the highway around the city begins to enter the period of overhaul. However, because of the extremely important traffic function of the highway around the city, it is carrying heavy traffic volume. The overhauling construction will have a greater impact on the regional highway network and the urban expressway network. In order to minimize the mutual interference between the construction and the traffic, and to ensure the safety and smooth of the road network during the construction of the highway tunnel around the city, It is imperative to study traffic organization during the construction of high-speed tunnel around the city. First of all, this paper analyzes the characteristics of the surrounding high-speed tunnel, including the characteristics of the surrounding high-speed tunnel, the structure characteristics of the surrounding high-speed tunnel and the traffic characteristics of the tunnel under the influence of construction, and so on. At the same time, referring to the overhauling construction technology of expressway section, the major repair construction plan of the high speed tunnel around the city is determined, and the traffic organization plan of the tunnel construction area is designed according to the construction plan under different construction plans. The advantages and disadvantages of different traffic organization schemes and their application are analyzed. Then, through the selection of key influencing factors, the direct and indirect influence scope and intensity of overhaul construction are analyzed, and according to the characteristics of different tunnel overhaul construction schemes, This paper analyzes and studies the different traffic organization strategies and corresponding traffic management facilities in the construction area and the periphery, and forms a set of complete traffic organization plan for the overhaul of the high speed tunnel around the city, and combines the characteristics of the urban traffic. Select appropriate evaluation methods and some key indicators to evaluate the traffic organization plan in the construction of highway tunnel overhaul, judge the feasibility and implementation effect of the traffic organization plan, and provide the basis for the improvement of the scheme. At the same time, it also reduces the risk of the implementation of the scheme and maximizes the utility of the implementation of the traffic organization plan. Finally, combined with the construction of the high-speed Huangheshan Tunnel around Hangzhou, the tunnel construction plan is designed, as well as the traffic organization plan of the construction area and the periphery during the tunnel construction. This paper makes an empirical analysis on the traffic diversion organization scheme of the overhauling construction of the high speed tunnel around the city, and according to the evaluation index of the traffic organization scheme of the construction of the high speed tunnel around the city, the traffic organization scheme of the tunnel overhaul construction is evaluated and analyzed. Finally, a complete traffic organization scheme for the construction of high-speed tunnel around the city is formed, and the effect is good.
