【正文】 遼寧科技大學(xué)本科生畢業(yè)設(shè)計 第 I 頁 摘 要 本次設(shè)計為高速公路綜合設(shè)計路段，此路段位于 煙臺 境內(nèi)，根據(jù) 設(shè)計公路的交通量、地形特征以及使用任務(wù)和性質(zhì)，確定公路等級為高速 公路。在此基礎(chǔ)上，結(jié)合沿線自然條件與主要技術(shù)指標，進行路線方案論證與比選，最終確定一個最佳方案進行詳細技術(shù)設(shè)計。其主要內(nèi)容包括：路線的平、縱、橫設(shè)計，路基、路面設(shè)計和排水設(shè)計以及交通設(shè)施設(shè)計 , 并完成施工圖設(shè)計階段應(yīng)完成的各種圖、表及設(shè)計說明書。本設(shè)計嚴格依據(jù)規(guī)范的各項指標進行，最后確定本高速公路設(shè)計速度為 100km/h，路基寬 26m，雙向 四車道，路線全長 ，路面為瀝青混凝土面層，厚 18cm，全線共設(shè)計了 2 個平曲線、 3 個豎曲線、 1 條隧道 、 6 個鋼筋混凝土通道 。 關(guān)鍵詞 高速公路； 平曲線 ； 豎曲線 ； 路基 ； 路面 遼寧科技大學(xué)本科生畢業(yè)設(shè)計 第 II 頁 Abstract This express section is located at the east of Chongqing province， which is heavy highland area． According to the requirements of mountain highway design, the grading of express is based on the traffic volume, the use of task and nature. Then, through bining natural conditions along and the main technical indicators, evaluating and electing the route, this express section ultimately determine the best option for a detailed technical design. Its main contents include: plane design, vertical curve design, transect curve design, roadbed design, road surface design, drainage design and traffic facilities design. In addition, all kinds of the figures, tables, and specifications are given in detail in this paper. After conducting technical feasibility studies accord to specification, the designing velocity is 100 km / h. The width of the roadbed is 26 meters with four twoway lanes. The length of the road is . The road’s surface is paved by asphalt concrete. There are two plane curves, two vertical curves, a total of two bridges, five reinforced concrete channel.
