【正文】 ，根據(jù)該路形的性質(zhì)、地形、地物、水文等自然條件的特點(diǎn)，依據(jù)《公路工程技術(shù)標(biāo)準(zhǔn)》 (JTG B012021)交通部頒發(fā)的主要有關(guān)技術(shù)指標(biāo)完成，在設(shè)計(jì)中全部采用最新標(biāo)準(zhǔn)和規(guī)范。完成了以下路基 路面 I Abstract This design according to the given material. through the analysis on the original data, according to the nature of this route, topography, geophysics, hydrology and other natural conditions, according to the characteristics of the highway engineering technical standards (2021), etc B01 JTG related technical index issued by the ministry of plete in the design, all adopt the new standards and norms. Completed the following content: according to the given up end, select the appropriate control points, according to the average spacing and selected contour ZongPo, preliminary develop feasible route schemes, as amended, identify meet the standards requirements of the horizontal alignment。 According to the highway route design rules (JTG D202021) regulation (maximum ZongPo, restricted slope length etc), bining the elevation control and economic points, to determine the route alignment design line。 According to the highway rating and terrain conditions, roadbed design。 According to the highway rating and traffic, determine the pavement structure types and plete the pavement design, the highway route of CAD software and puter graphics。 Keywords route Subgrade Pavement II 目 錄 摘 要 .......................................................................................................................
