【摘要】：目前，巫山縣農(nóng)村公路技術(shù)等級普遍低，農(nóng)村公路標(biāo)準(zhǔn)低，嚴(yán)重制約了當(dāng)?shù)亟?jīng)濟社會的發(fā)展，為了更好地指導(dǎo)巫山縣農(nóng)村公路的建設(shè)，本文對巫山縣農(nóng)村公路線形技術(shù)標(biāo)準(zhǔn)和路面典型結(jié)構(gòu)進行了系統(tǒng)的研究。 本文通過對巫山縣地形地貌、氣候條件、土壤地質(zhì)狀況、路面狀況等方面進行大量的調(diào)查，分析了巫山縣農(nóng)村公路存在的問題，為建立巫山縣農(nóng)村公路線形指標(biāo)和典型路面結(jié)構(gòu)提供了基本依據(jù)。再通過對現(xiàn)有巫山縣農(nóng)村公路交通量及交通量組成研究分析，確定了巫山縣農(nóng)村公路的等級和對當(dāng)?shù)亟煌ㄟM行設(shè)計參數(shù)，參照規(guī)范，制定了巫山縣各等級農(nóng)村公路的線形技術(shù)指標(biāo)。此外，對巫山縣的路面狀況和路用材料進行了調(diào)查，結(jié)合巫山縣農(nóng)村公路路面結(jié)構(gòu)實際設(shè)計原則，借鑒國內(nèi)外路面結(jié)構(gòu)設(shè)計方法，確定出了適合不同交通量等級的農(nóng)村公路瀝青、水泥典型路面結(jié)構(gòu)形式。最后，，利用ABAQUS有限元軟件和理論方法分析不同尺寸、不同厚度、不同軸載條件下的水泥板底產(chǎn)生最不利彎拉應(yīng)力和溫度應(yīng)力，從而確定出經(jīng)濟合理、技術(shù)可行的路面結(jié)構(gòu)組合和面層厚度。同時利用ABAQUS對不同層厚的瀝青路面結(jié)構(gòu)進行仿真分析，確定了巫山縣農(nóng)村公路的典型瀝青路面形式。 本文的研究成果針對性強、合理可靠、經(jīng)濟使用，對巫山縣農(nóng)村公路的建設(shè)具有很好的參考價值。
[Abstract]:At present, the technical grade of rural highway in Wushan County is generally low, and the standard of rural highway is low, which seriously restricts the development of local economy and society. In order to better guide the construction of rural highway in Wushan County, In this paper, the technical standards of highway alignment and typical pavement structure in Wushan county are systematically studied. Based on a large number of investigations on the landforms, climatic conditions, soil geological conditions and road surface conditions in Wushan County, this paper analyzes the problems existing in the rural roads of Wushan County. It provides the basic basis for establishing the linear index and typical pavement structure of rural highway in Wushan County. Through the research and analysis of the traffic volume and traffic volume composition of the rural highway in Wushan County, the grade of the rural highway and the design parameters of the local traffic are determined, referring to the specification. The linear technical index of every grade of rural highway in Wushan county has been formulated. In addition, the pavement condition and road materials of Wushan county are investigated. Combined with the practical design principles of rural highway pavement structure in Wushan county, the design methods of pavement structure at home and abroad are used for reference. The typical pavement structure forms of rural highway asphalt and cement suitable for different traffic levels are determined. Finally, the ABAQUS finite element software and theoretical method are used to analyze the most unfavorable bending tensile stress and temperature stress under the conditions of different size, different thickness and different axial load, so as to determine the economy and rationality. The technology is feasible for pavement structure combination and surface thickness. At the same time, ABAQUS is used to simulate and analyze the asphalt pavement structure of different layer thickness, and the typical asphalt pavement form of Wushan rural highway is determined. The research results in this paper have strong pertinence, reasonable and reliable, economic use, and have a good reference value for the construction of rural highway in Wushan County.
