【正文】 蘭州交通大學畢業(yè)設(shè)計（論文） I 引 言 初步設(shè)計是進行公路和城市道路設(shè)計施工建設(shè)的必要環(huán)節(jié)，此環(huán)節(jié)設(shè)計的好壞直接影響著以后整個工程的施工進度和質(zhì)量。它是通過所給的地形圖在充分考慮當?shù)氐牡匦蔚匚飾l件并且結(jié)合各種規(guī)范而進行的道路的綜合設(shè)計。它一般包括道路的平縱橫設(shè)計、防護設(shè)計、排水設(shè)計、路基設(shè)計、路面設(shè)計、交通工程設(shè)施設(shè)計等。本次通過設(shè)計實例――廣西雷江 鳳靈新建二級公路初步設(shè)計，使我們能掌握道路設(shè)計過程的一些基本的原則，了解道路基本設(shè)計的內(nèi)容和程序等。 通過此次畢業(yè)設(shè)計，可以使我們在如何進行公路施工圖設(shè)計方面進行一次全面的、系統(tǒng)的訓練，使我 們了解公路施工圖設(shè)計所包括的工作內(nèi)容、工作程序、施工圖設(shè)計文件所包括的內(nèi)容及文件的編制辦法等，為今后從事公路工程設(shè)計工作打下良好的基礎(chǔ)。通過畢業(yè)設(shè)計，既有助于提高我們綜合運用知識的能力，同時也有助于以后在工作崗位能很快地適應(yīng)工作環(huán)境。 本次設(shè)計中的主要任務(wù)是： ，選定 廣西雷江 鳳靈二 級公路的路線設(shè)計方案，根據(jù)道路技術(shù)等級和道路技術(shù)標準，計算確定相關(guān)參數(shù)； 繪制 廣西雷江 鳳靈二 級 公路路線 平、縱、橫斷面設(shè)計圖，路基路面結(jié)構(gòu)圖； 進行該道路曲線要素計算、編制相關(guān)計算結(jié)果表 。 路基路面設(shè)計。 本畢業(yè)設(shè)計是嚴格在各種規(guī)范的指導之下進行的，內(nèi)容嚴謹、詳細，具有一定的參考價值和實用價值。 2021年 6月 蘭州交通大學畢業(yè)設(shè)計（論文） II 摘要 雷靈 二級公路是全國公路往中的一條主要干線，對 雷靈 地區(qū)的經(jīng)濟發(fā)展起著很大的作用。本路線 途經(jīng)山嶺重丘區(qū)，本著安全、經(jīng)濟、實用、美觀的原則，對該路段進行施工圖設(shè)計。 雷靈 公路施工圖設(shè)計是在所在地區(qū)的地形、地質(zhì)、氣候的影響下，按照設(shè)計規(guī)范進行的。本次設(shè)計的內(nèi)容有：平面線設(shè)計、縱斷面設(shè)計、橫斷面設(shè)計 。平面線設(shè)計包括紙上選線、定線，圓曲線、緩和曲線參數(shù)設(shè)定，直線設(shè)計等；縱斷面設(shè)計包括拉坡、豎曲線設(shè)計等，超高的設(shè)定一滿足了設(shè)計要求的 8%之內(nèi)，在豎曲線設(shè)計時，應(yīng)注意行車視距和視線誘導問題即滿足“平包縱”，合成坡度也要滿足規(guī)范要求；橫斷面設(shè)計時，使行車更加舒適，為確保道路的使用年限，在路段上還做了 防護和排水設(shè)計。排水設(shè)計包括路基排水和路面排水，路面設(shè)計又有邊溝設(shè)計和截水溝設(shè)計和路拱排水。 施工圖是工程的重要組成部分，可以使道路的實用性和經(jīng)濟性得到更好的保證，同時，也要求道路的美觀性和實用性、經(jīng)濟性相結(jié)合。 關(guān)鍵詞 ： 施工圖；路基設(shè)計；平面；橫斷面；縱斷面； 蘭州交通大學畢業(yè)設(shè)計（論文） III Abstract Working properly to hope second class highway is the national highway go toward medium of a main trunk line, to work properly the economic development of hope the region to rise very big route goes by way of the heavy area of hillock of mountain range, being in the light of the safety, economy, practical, the principle of the beauty, carry on the construction to the road39。s segment diagram design. Working properly to hope the highway construction diagram design is under the influence of the geography, geology, weather of the place region, carrying on according to the design norm contents for design have:The flat surface line design, vertical section design, cross section design, block the soil wall design and the engineering quantity calculations and grounds square flat surface line the design includes the paper select line, settle line, a curve, the mitigation curve parameter enactment, straight line design etc.。The vertical section design includes to pull the gradient , Set extremely highly on satisfying 8% of the design request inside the vertical curve design...etc., at the vertical curve design, at the request of notice to go the car to see to be apart from to induce the problem to satisfy a vertical curve namely with view, synthesize the slope also want satisfy the norm。When the cross section design, considered the extremely high constitution, make go the car more fortable, in order to insure the usage time limit of the road, still did the protection and drain the design on the road segment. Drain the design to include the roadbed catchment and roads to face the catchment, the road faces the design and has the side ditch design and cuts the drain design and the road arch catchments. The construction diagram is the importance of the engineering to constitute the part, can make the function and economy of the road get the better assurance, at the same time, also request the beauty and function, economy of the road to bine together. Keywords: Diagram design； Road design； Flat surface design； Vertical section design；Cross section design. 蘭州交通大學畢業(yè)設(shè)計（論文） I 目錄 引 言 ......................................................................................................................................
