With its design speed of 80km / h and twoway fourlane , The length of this road is 2800 m . The design includes plane design, vertical section design, cross section design, roadbed and retaining wall design, subgrade and pavement selection mix formulation and checking design and structure layer thickness of the waterproof and drainage design, culvert design, pavement materials. Graphic design with a flat curve, longitudinal section design with a vertical curve. Subgrade width of , maximum superelevation 6%. Subgrade and pavement drainage facilities in a ditch, ditches, drains, and so on. The bridge and roadbed width, using prefabricated prestressed concrete continuous box girder bridge. A culvert two, respectively for the reinforced concrete box and reinforced concrete pipe culvert. A culvert two, respectively for the reinforced concrete box and reinforced concrete pipe culvert. Pavement design includes determining thickness and structure design of pavement type, the design of pavement with asphalt concrete pavement, pavement structure design of 5 layers are fine 4cm asphalt concrete, 6cm mediumgrained asphalt concrete, 8cm coarse asphalt concrete, cement stabilized gravel, 20cm 20cm of lime flyash gravel. The design of the pavement structure design software checking out the structural layer thickness meets the requirements. Flat, vertical, horizontal threedimensional design generates the corresponding chart of hintsoftroad software. Key words: flat, vertical, crosssectional design, the design of embankment, bridge design, pavement structure design, Weft of road 河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 目錄 — I— 目 錄 前 言 ....................................................... 1 1 緒論 ...................................................... 2 設(shè)計(jì)資料 .................................................... 2 道路所在地區(qū)的氣象資料 ................................ 2 沿線的工程地質(zhì)及水文地質(zhì)情況 .......................... 2 沿線的植被及土壤分布情況 .............................. 2 道路建筑材料及分布情況 ................................ 2 交通量資料 ............................................ 2 設(shè)計(jì)標(biāo)準(zhǔn) .................................................... 3 2 平、縱、橫三維設(shè)計(jì) ......................................... 5 選線 ........................................................ 5 平面線形設(shè)計(jì) ................................................ 5 平曲線線形設(shè)計(jì)一般原則 ................................ 6 平縱橫綜合設(shè)計(jì) ........................................ 6 路線方案比選 .......................................... 7 平面線形要素組合計(jì)算 .................................. 8 樁號(hào)復(fù)核與驗(yàn)算 ........................................ 9 縱斷面設(shè)計(jì) ................................................. 10 縱斷面設(shè)計(jì)概述 ....................................... 10 縱坡設(shè)計(jì) ............................................. 11 平、縱線形組合設(shè)計(jì) ................................... 11 豎曲線 ............................................... 12 橫斷面設(shè)計(jì) ................................................. 14 橫斷面組成及其類(lèi)型 ................................... 14 橫斷面設(shè)計(jì)步驟 ....................................... 16 平曲線加寬設(shè)計(jì) ....................................... 17 超高設(shè)計(jì) ............................................. 17 超高的計(jì)算 ........................................... 19 土石方的計(jì)算和調(diào)配 ................................... 19 3 路基設(shè)計(jì) .................................................. 21 路基設(shè)計(jì) ................................................... 21 路基排水設(shè)計(jì) ............................................... 24 路基防護(hù)與加固 ............................................. 24 4 擋土墻設(shè)計(jì) ................................................ 27 擋土墻的構(gòu)造 ............................................... 27 擋土墻的布置 ............................................... 28 河南城建學(xué)院本科畢業(yè)設(shè)計(jì)(論文) 目錄 — II— 擋土墻土壓力計(jì)算與穩(wěn)定性驗(yàn)算 ............................... 29 5 路面結(jié)構(gòu)設(shè)計(jì) .............................................. 32 基本資料 ................................................... 32 路面結(jié)構(gòu)層分層 ............................................. 32 面層 ................................................. 33 基層 ................................................. 33 墊層 ....................
