【正文】 g. The design thesis to be familiar with topographic maps and to the original data, and analysis of the distribution of its topography, the height difference, canals, and arable land, buildings, etc.. Then line selection, program parison and selection, line, graphic design, profile design, the crosssectional design, earthwork calculations, of Earthwork, slope design, the design of the asphalt pavement. Keywords: roadbed。然后進行選線，方案比選，路線平面設(shè)計，縱斷面設(shè)計，橫斷面設(shè)計，土石方計算， 土方調(diào)配，邊坡設(shè)計，瀝青路面設(shè)計 。 三者是相互關(guān)聯(lián)， 既分別進行，又綜合考慮。中線上任意一點的法向切面是道路在該點的橫切面。路線在水平面上的投影稱作路線的平面。它是由路基、路面、橋梁、涵洞、和沿線設(shè)施所組成的線形構(gòu)造物。 陜西省商州至陜豫界一級公路施工設(shè)計 第 1 頁 共 37 頁 畢業(yè)設(shè)計（論文） 題目： 陜西省商州至陜豫界一級公路施工設(shè)計圖 陜西省商州至陜豫界一級公路施工設(shè)計 第
