1、沈陽建筑大學(xué)畢業(yè)設(shè)計(jì)摘要根據(jù)已有的設(shè)計(jì)資料和中國交通部設(shè)計(jì)要求以及部頒標(biāo)準(zhǔn)和規(guī)范,對遼寧省境內(nèi)大連至莊河二級公路K0+000~K4+820.041段進(jìn)行了路基路面綜合設(shè)計(jì)。設(shè)計(jì)車速為60km/h,雙向二車道。本次畢業(yè)設(shè)計(jì)的主要內(nèi)容包括:路線平面設(shè)計(jì)、路線縱斷面設(shè)計(jì)、路基橫斷面設(shè)計(jì)、路基路面排水設(shè)計(jì)、路面結(jié)構(gòu)設(shè)計(jì)、小橋設(shè)計(jì)、施工組織設(shè)計(jì)以及概預(yù)算的編制等。在平面設(shè)計(jì)中,考慮到是平原微丘區(qū)新建公路,在設(shè)計(jì)線路上選了五個(gè)交點(diǎn),曲線半徑分別為300m,250m,300m,500m,900m,緩和曲線長度為130m,90m,10
2、0m,150m,150m,均符合規(guī)范要求。在縱斷面設(shè)計(jì)中,全線共設(shè)五個(gè)變坡點(diǎn),豎曲線半徑分別為15000m,8000m,15000m,7000m,20000m。橫斷面設(shè)計(jì)中選一公里長的路線做為設(shè)計(jì)對象,每20米做一個(gè)橫斷面圖,邊坡坡度為1:1.5。在小橋涵設(shè)計(jì)中,主要進(jìn)行了一座17米小橋的上部結(jié)構(gòu)的計(jì)算和驗(yàn)算。采用手工和程序相結(jié)合的辦法按照規(guī)范規(guī)定進(jìn)行路面結(jié)構(gòu)設(shè)計(jì)。根據(jù)道路施工情況,對施工人員、施工機(jī)械、工程量安排等進(jìn)行了施工組織設(shè)計(jì)。另外還用同望軟件編制了設(shè)計(jì)范圍內(nèi)路基和路面的預(yù)算文件。本設(shè)計(jì)部分圖紙采用CAD系統(tǒng)繪
3、制,部分?jǐn)?shù)據(jù)采用Excel表格計(jì)算顯示。此次設(shè)計(jì)使我在專業(yè)知識方面得到了綜合訓(xùn)練和提高,增強(qiáng)了獨(dú)立分析和解決問題的能力,取得了良好的效果。關(guān)鍵詞:二級公路;路基;路面;排水設(shè)計(jì);橋梁設(shè)計(jì);綜合設(shè)計(jì)6沈陽建筑大學(xué)畢業(yè)設(shè)計(jì)AbstractAccordingtothetechnicalstandardsandspecificationsforhighwaydesignpublishedbytheMinistryofCommunicationsofChina,thecomprehensivedesignofhighwaysub
