某山区二级公路综合设计 摘 要 本项目位于江西省最南端的龙南县，路线走向大致由北向南而行，整个地形特征呈中部高，两端低，道路沿线路基边坡相对稳定，无不良地质路段，道路所经之处基本都是山岭和荒坡，占用可耕种土地资源较少。原有道路为山区三级公路，路面破损严重，路基宽7.5米，已不适应当前经济发展的需要，改建道路要求尽量利用旧路。 路线全长为6.48Km，负责设计的路段为桩号从K0+000至K3+369.484，长3369.484 米，采用双向两车道形式，无中央分隔带，路基宽度为10m，设计时速为60km/h，路面结构采用沥青混凝土路面。 这次设计充分运用AUTOCAD、海地公路优化设计软件进行道路设计计算基础图，运用HPDS2006路面结构设计软件进行路面结构的设计及验算。 关键词：二级公路；平面设计；路面设计；挡土墙设计；排水设计。Synthesis design of a mountain secondary road Abstract This design for a secondary highway design in mountainous area.Long Naxian on the southernmost tip of this project is located in jiangxi province, the route runs roughly from north to south and central the terrain feature is high, low, on both ends along the road subgrade slope is relatively stable, no bad geological sections of roads are basic in the path of all the mountains and slope, occupy less arable land resources. Original road level 3 highway in the mountain areas, road surface damage is serious, roadbed width of 7.5 meters, has not adapt to the needs of current economic development, rebuilding roads requirements as far as possible use of old road. Line length of 6.48 Km, is responsible for the design sections for the pile number from K0 + 000 to K3 + 369.484, and 3369.484 meters long, using two-way two-lane form, without the median, roadbed width of 10 m, the design speed of 60 Km/h, pavement structure using asphalt concrete pavement This design not only makes us understand the various steps of the construction of a road, but also the skilled use of AUTOCAD drawings and also mastered the use of software for optimization design of roads in Haiti. In addition to the graduation design is also important, as college students before graduation walkthrough, gives us a smooth path to jobs, but when your responsibility is of great significance. Key words: secondary road; graphic design; pavement design for the retaining wall design of plumbing design.目录 第一章 设计总说明 5 1.1路线及工程概况 5 1.2 沿线气候、水文特征、地形地震地理及其与公路的关系 5 1.3 沿线材料分布情况 6 1.4 环境保护 6 1.5 新技术采用及计算
