公路施工圖設(shè)計(jì)

1、1公路施工圖設(shè)計(jì)摘要本畢業(yè)設(shè)計(jì)為公路施工圖設(shè)計(jì)。福白公路起于福田寺，止于白螺，是一條平原區(qū)二級公路，雙向兩車道，設(shè)計(jì)時(shí)速60kmh，設(shè)計(jì)里程約7.1km。本畢業(yè)設(shè)計(jì)要求基于實(shí)測地形圖以及相關(guān)的補(bǔ)充資料，根據(jù)道路勘測設(shè)計(jì)基本原則以及路基路面工程基本理論，綜合考慮當(dāng)?shù)氐募夹g(shù)和經(jīng)濟(jì)條件，嚴(yán)格按照施工圖設(shè)計(jì)過程進(jìn)行獨(dú)立作業(yè)，主要包括路線設(shè)計(jì)、路面結(jié)構(gòu)設(shè)計(jì)以及路基處理方案設(shè)計(jì)，各項(xiàng)技術(shù)指標(biāo)均要滿足相關(guān)規(guī)范的要求。本設(shè)計(jì)運(yùn)用緯地5.88道路設(shè)計(jì)軟件

2、進(jìn)行道路路線設(shè)計(jì)。本設(shè)計(jì)標(biāo)段全線總長7304.526m。該路線包含3個(gè)平曲線，最大半徑340m，最小半徑270m；9個(gè)豎曲線最大半徑18200m，最小半徑12600m；1座沿途構(gòu)造物橋梁。路基寬度10m（土路肩0.75m2，硬路肩0.75m2，行車道3.5m2），雙向兩車道。不設(shè)超高路段的行車道及硬路肩路拱橫坡采用2.0%，土路肩路拱橫坡3.0%。設(shè)計(jì)填方總量35782m3，挖方總量36530m3，填挖基本平衡，且路基穩(wěn)定性好，不需設(shè)置

3、擋土墻，主要采用植物防護(hù)。本設(shè)計(jì)運(yùn)用HPDS路面設(shè)計(jì)軟件進(jìn)行路面結(jié)構(gòu)設(shè)計(jì)。路面材料采用瀝青混凝土結(jié)構(gòu)，選用瀝青混凝土材料。路面上面層采用4cm厚的細(xì)粒式瀝青混凝土AC13，下面層采用6cm厚的中粒式瀝青混凝土AC20，基層采用20cm厚的水泥穩(wěn)定碎石，墊層采用20cm厚的水泥粉煤灰碎石。關(guān)鍵詞：施工圖設(shè)計(jì)；平原區(qū)二級公路；路面結(jié)構(gòu)設(shè)計(jì)；縱斷面設(shè)計(jì)；橫斷面設(shè)計(jì)；瀝青路面設(shè)計(jì)3目錄1緒論...........................
