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，，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。
，负责设计的路段为桩号从K0+000至K3+，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。

Synthesis design of a mountain secondary road
Abstract
This design for a secondary highway design in mountainous 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 ,勿做商业用途文档为个人收集整理，来源于网络
Line length of Km， is responsible for the design sections for the pile number from K0 + 000 to K3 + 369。484, and 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 g
