【導讀】道路等級是某山嶺區(qū)三級公路，三級公路一般能適應(yīng)按各種車輛折合成中型載重汽車的遠景設(shè)計年限年平均晝夜量為1000～4000輛。此次設(shè)計為期12周，指導教師是劉穎和謝石連等老師。在設(shè)計工程中會運用到道路勘測設(shè)計、路基路面工程等知識，對規(guī)定道路進行選線、定線、平面、縱斷面、橫斷面、路基路面等的計算?？v斷面的設(shè)計，橫向比例是1：2000，縱向比例是1：500，其中包括點繪縱斷面地面線，設(shè)計縱坡和豎曲線，計算設(shè)計標高等。本次設(shè)計的道路總長K3+，地勢在一開始就較陡峭，填挖量就大。在設(shè)計橫斷面時，要注意平面圖上的緩和段的加寬超高，而且在設(shè)計過程中要滿足《規(guī)范》上的規(guī)定。路線定線后，要根據(jù)路線交點的實際情況，酌情選定圓曲線半徑。為了提高公路使用質(zhì)量，各級公路的圓曲線應(yīng)盡量采用較大的半徑。
