In this design the highway length is 3000m,the car speed is 80km/h , bi directional and four lane and setting Central Separate Belt. Firstly analysis the traffic conditines,to find the corresponding technical specifications, ascertain the level of highway design and various parameters what we need 。secondly ascertain two Route schemes at 1:2022 topographic map, bined with the application of natural condition and main technical indices , make route project argumetntation and selection, select the optimal design and make detailed technical design, contents include: the flat, the longitudinal and the lateral design ,the route rrainage design, retaining wall design and pavement structure plete various chart and design manuals construction which we should finish in design stage. Key Words: first class highway。 horizontal curve。 vertical curve。 drainage。 subgrade。 retaining wall。 asphalt pavement。 目錄 目 錄 中文摘要 .................................................
