文档介绍：摘要 I 福建 306 省道施工图设计摘要本次设计是福建省 306 省道的改造工程,公路全长近 3000 米。该公路沿线地形比较复杂,多为山岭,沟谷,河流,并有多处工厂。沿线地势变化比较明显, 全线海拔在 670 米至 780 米之间,起终点高差比较大。该公路的预计建成后第一年的交通量为 3889 辆/日,年平均增长率为 8%,设计年限为 15, 。根据规范要求, 因此应设为二级公路,但同时又考虑到地形比较复杂的原因,设计速度定为 40km/h 比较合理。本次设计本着“和谐、人性、环保、安全”的设计原则,根据国家最新设计规范进行设计。道路部分包括路线线形方案的选择、平面设计、纵断面设计、横断面设计、路面结构设计、路基排水设计、交通沿线设施设计。设计成果包括路线平面图、路线纵断面图、路基横断面图、路基路面结构图、道路技术经济指标表、直曲转角表、路基土石方数量、路基设计表、路基工程数量表等等。关键词:二级公路;设计原则;设计成果 A bstract II 306 provincial highway construction drawing design inFuJian province Abstract This design isthe 306 provincial highway reconstruction project in fujian province,Road ofnearly 3000 miles topography plicated along the highway,Much asmountains, valleys, rivers, and there are many obvious along the terrain change,Across the board between 670 meters to780 meters above sea level,The end point elevation difference highway isexpected inthe first year after pletion ofthe traffic volume of3889 /day,The average annual growth rate of8,Design offixed number ofyear for tothe specification requirements,Should beset asthe secondary road,But atthe same time, considering the terrain plex,Design speed is40km/h isquite reasonable. The design principle ofthis design isinline with harmonious 、 humanity 、environmental 、safety,According tothe national design specification for latest section including the selection of the route scheme, The plane design, Profile design ,Cross-sectional design ofpavement structure ,design ofsubgrade drainage ,design Along the traffic facilities .Design results include Route plan route longitudinal profile Subgrade cross sectional drawing road subgrade pavement structure oftechnical and economic indicators table Straight curved corner table Number ofthe earth work roadbed subgrade engineering design table table, etc. Key words:Secondary road; design philosophy ;Design results A bstract III 目录目录摘要.........................................................................
