Starting point stake number is K0+, ending point stake number is K1+ and the whole length of this road is meters. The road grade is urban secondary trunk, class Ⅲ , the design speed is 30km/h. This design includes routes` plane, longitudinal section and horizontal section, asphalt pavement, drainage design and intersection design. The scheme of this route bined the Longterm blueprint of Hunan University of Science and Technology and facilities along the road such as apartment of students, canteen, teaching buildings and so on. It follows the general principles of the urban road design. The design of vertical curve considered students` daily travel, so the longitudinal slope should not be too sharp. But on the other hand, parts of the route have large height differences, and the limit of the elevation of existing buildings along both sides, so, the maximum longitudinal slope is % and this more or less makes some trouble to nonmotor vehicle driving. Key words: Horizontal curve, Subgrade, Earthwork, Retaining wall, Asphalt Concrete, Drainage. 湖南科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） i 目錄 第一章 前言 ......................................................................................................................... 1 第二章 工程概況及設(shè)計(jì)標(biāo)準(zhǔn) ........................................................................................ 3 工程概況 ...................................................................................................................... 3 路線起訖點(diǎn) ........................................................................................................... 3 地形、地質(zhì)、氣候、水文等自然特征 ............................................................... 3 施工條件 ............................................................................................................... 3 設(shè)計(jì)標(biāo)準(zhǔn) ...................................................................................................................... 3 設(shè)計(jì)依據(jù) ............................................................................................................... 3 主要技術(shù)指標(biāo)及參數(shù) ........................................................................................... 3 第三章 平面設(shè)計(jì) ................................................................................................................ 5 選線 .............................................................................................................................. 5 選線的原則 ........................................................................................................... 5 選線的步驟和方法 ............................................................................................... 5 平曲線設(shè)計(jì) .................................................................................................................. 5 平面線形設(shè)計(jì)的一般原則 ................................................................................... 5 設(shè)計(jì)參數(shù)的確定 ................................................................................................... 6 平面線形要素的組合類 型 ................................................................................... 6 平曲線要素的計(jì)算 ............................................................................................... 6 行車視距保證 .............................................................................................................. 9 逐樁坐標(biāo)計(jì)算 ............................................................................................................ 10 直線上中樁坐標(biāo)的計(jì)算 ..................................................................................... 10 設(shè)緩和單曲線中樁坐標(biāo)計(jì)算 ............................................................................. 11 第四章 縱斷面設(shè)計(jì) ......................................................................................................... 13 縱坡及坡長(zhǎng)設(shè)計(jì) ........................................................................................................ 13 縱坡設(shè)計(jì)的一般要求 ......................................................................................... 13 平出線與豎曲線的組合一般原則 ..................................................................... 13 設(shè)計(jì)依據(jù) ............................................................................................................. 13 縱斷面設(shè)計(jì)步驟 ................................................................................................. 14 豎曲線設(shè)計(jì) ................................................................................................................ 15 湖南科技大學(xué)本科生畢業(yè)設(shè)計(jì)（論文） ii 設(shè)計(jì)技術(shù)規(guī)范 ..................................................................................................... 15 豎曲線要素計(jì)算 ................................................................................................. 15 第五章 橫斷面設(shè)計(jì) ......................................................................................................... 17 概述 ............................................................................................................................ 17 橫斷面設(shè)計(jì) ................................................................................................................ 17 一般規(guī)定 ............................................................................................................. 17 橫斷面形式 .........................
