河南理工大學本科畢業(yè)設(shè)計 摘要 I 摘 要 本次設(shè)計是 長垣至滑縣 一級公路第十五標段的設(shè)計。公路全長 2995m,設(shè)計車速為 80km/h,雙向 四 車道,設(shè)置中央分隔帶。 設(shè)計中主要包括以下幾個階段: ( 1) 主線平面設(shè)計:全線長 2995 米 ,在這段路上選了 三 個交點,交點半徑均 為 400m。 ( 2) 縱斷面設(shè)計:考慮滿足排水的最小縱坡要求進行了路線縱斷面設(shè)計。全線共有 兩 個變坡點,半徑 均 為 10000m。 ( 3) 橫斷面設(shè)計:以樁號為基本點,進行了橫斷面設(shè)計、路基設(shè)計表設(shè)計、土石方計算、排水平面設(shè)計等。 ( 4) 路面結(jié)構(gòu)設(shè)計:采用手工和程序相結(jié)合的辦 法進行了路面結(jié)構(gòu)設(shè)計。 ( 5) 預(yù)算:編制了 路線范圍內(nèi)路基和路面部分的預(yù)算文件 。 大部分圖紙使用 CAD 繪制,部分數(shù)據(jù)使用 EXCEL 計算。 關(guān)鍵詞 : 主線平面設(shè)計、縱斷面、橫斷面、路面結(jié)構(gòu)設(shè)計 河南理工大學本科畢業(yè)設(shè)計 摘要 II Abstract This design is Huaxian to Changyuan fifteenth Sections of arterial road design. the length of this road which we design is 2995m, the speed is 80km/h, twoway fourlane andset up the central of separation strip. ( 1) Master line plane design: long line in this election, three points on the road, intersection radius of 400m ( 2) Longitudinal section design: Considered that satisfied draining water the smallest lengthwise grade request to carry on the route longitudinal section design. The entire line altogether has three changes the slope spot, Radius of 10000m。 ( 3) Cross section design: Take the station number as the fundamental point, has carried on the cross section design, the grade location table design, the cubic meter of earth and stone putation, the draining water plane design and so on. ( 4) Pavement structure design: Uses the means which the handwork and the procedure unify to carry on the pavement structure design. ( 5) Budget: Has established in the hole scope the roadbed and the road surface part budget document. The majority of blueprints use the CAD plan, the partial data use EXCEL to calculate. Key word: Master line plane design, longitudinal section, cross section, pavement structure design 河南理工大學本科畢業(yè)設(shè)計 目錄 III 目錄 摘 要 .............................................................................................................................I 目錄 ............................................................................................................................
