【摘要】：隨著交通事業(yè)的不斷發(fā)展,往往原有低等級的道路因為病害或者交通量要求,已經(jīng)越來越不能滿足道路交通的要求。為了更好的完善交通路線,需要對現(xiàn)行的道路進行改擴建,使其能滿足現(xiàn)行交通要求。而現(xiàn)行的舊路改建問題涉及因素眾多,最佳工程方案確定往往較為困難。普通國道改擴建項目不同于新建項目,受既有道路限制,需考慮對既有路線的擬合、新舊路基拼接、新舊橋梁拼接等因素的影響。因此,開展普通國道路基和橋梁拼接技術(shù)研究,對提高普通國道通行能力和綜合服務(wù)水平,具有重要的理論和實際意義。本文圍繞G223國道建設(shè),通過實地考察、文獻查閱、數(shù)值模擬等方法,分析普通國道新舊路基和橋梁拼接技術(shù)方案,主要內(nèi)容如下:首先,通過實地調(diào)研客觀分析G223國道建設(shè)發(fā)展過程中存在的制約因素,對國內(nèi)外普通干線公路加寬改擴建技術(shù)發(fā)展趨勢及普通干線公路改擴建方案的相關(guān)概念進行辨析,并對普通干線公路加寬改擴建技術(shù)研究現(xiàn)狀進行綜述,尋找普通干線公路加寬改擴建技術(shù)需要的各學(xué)科理論基礎(chǔ)。其次,以海榆東線(國道G223)國道改擴建示范工程項目為依托,參考了G223國道和其他省道改擴建的成功經(jīng)驗,并通過有限元軟件ANSYS、Midas-civil分別對路基和橋梁結(jié)構(gòu)進行空間計算分析,著重對普通國道的改擴建方案、新舊路基拼接、新舊橋梁拼接等關(guān)鍵技術(shù)進行了研究。最后,在上述工作基礎(chǔ)上,提出了我國普通國道改擴建方案的設(shè)計原則和方法,通過對普通國道改擴建工程特點的分析,總結(jié)出新舊路基拼接和新舊橋梁拼接的關(guān)鍵技術(shù)及相關(guān)處理方案。所做工作對普通國道路基和橋梁拼接技術(shù)方案的制定和優(yōu)化具有一定的參考意義。
[Abstract]:With the continuous development of transportation, the original low-grade roads are often unable to meet the requirements of road traffic because of diseases or traffic volume requirements. In order to better improve the traffic routes, the existing roads need to be rebuilt and expanded to meet the current traffic requirements. It is difficult to determine the best project plan. The reconstruction and expansion project of the common national highway is different from the new project, which is restricted by the existing road. It is necessary to consider the influence of the fitting of the existing road, the splicing of the old and new roadbed, and the splicing of the old and new bridges. Ability and comprehensive service level are of great theoretical and practical significance. This paper focuses on the construction of G223 national highway, through field investigation, literature review, numerical simulation and other methods, analyzes the common national highway new and old roadbed and Bridge splicing technology scheme, the main contents are as follows: First, through field investigation and objective analysis of G223 national highway construction and development process exists. Restricting factors, this paper discriminates the development trend of general trunk highway widening and extension technology at home and abroad and the related concepts of general trunk highway widening and extension scheme, and summarizes the current research situation of general trunk highway widening and extension technology, in order to find the theoretical basis of various disciplines needed for general trunk highway widening and extension technology. Relying on the demonstration project of rebuilding and expanding the national highway of Haiyu East Railway (G223), referring to the successful experience of rebuilding and expanding the national highway of G223 and other provincial highways, and through the finite element software ANSYS and Midas-civil, the spatial calculation and analysis of the subgrade and bridge structure are carried out respectively, focusing on the rebuilding and expanding scheme of the common national highway, the splicing of new and old subgrade, the splicing of new and old bridges. Finally, on the basis of the above work, the design principles and methods of the renovation and expansion schemes of the common national highways in China are put forward. Through the analysis of the characteristics of the renovation and expansion projects of the common national highways, the key technologies and relevant treatment schemes of the new and old roadbed splicing and the new and old bridge splicing are summarized. The formulation and optimization of foundation and Bridge splicing technology plan has certain reference significance.
