1、沈陽建筑大學(xué)畢業(yè)設(shè)計摘要根據(jù)已有的設(shè)計資料和中國交通部設(shè)計要求以及部頒標準和規(guī)范,對遼寧省境內(nèi)大連至莊河二級公路K0+000~K4+820.041段進行了路基路面綜合設(shè)計。設(shè)計車速為60km/h,雙向二車道。本次畢業(yè)設(shè)計的主要內(nèi)容包括:路線平面設(shè)計、路線縱斷面設(shè)計、路基橫斷面設(shè)計、路基路面排水設(shè)計、路面結(jié)構(gòu)設(shè)計、小橋設(shè)計、施工組織設(shè)計以及概預(yù)算的編制等。在平面設(shè)計中,考慮到是平原微丘區(qū)新建公路,在設(shè)計線路上選了五個交點,曲線半徑分別為300m,250m,300m,500m,900m,緩和曲線長度為130m,90m,100m,150m,150m,均符合規(guī)范要求。在縱斷面設(shè)計中,全線
2、共設(shè)五個變坡點,豎曲線半徑分別為15000m,8000m,15000m,7000m,20000m。橫斷面設(shè)計中選一公里長的路線做為設(shè)計對象,每20米做一個橫斷面圖,邊坡坡度為1:1.5。在小橋涵設(shè)計中,主要進行了一座17米小橋的上部結(jié)構(gòu)的計算和驗算。采用手工和程序相結(jié)合的辦法按照規(guī)范規(guī)定進行路面結(jié)構(gòu)設(shè)計。根據(jù)道路施工情況,對施工人員、施工機械、工程量安排等進行了施工組織設(shè)計。另外還用同望軟件編制了設(shè)計范圍內(nèi)路基和路面的預(yù)算文件。本設(shè)計部分圖紙采用CAD系統(tǒng)繪制,部分數(shù)據(jù)采用Excel表格計算顯示。此次設(shè)計使我在專業(yè)知識方面得到了綜合訓(xùn)練和提高,增強了獨立分析和解決問題的能力,取得
