摘 要
本毕业设计课题为邵新路A5合同段（K31+600-K35+100段）施工图设计。 本路段经过地区总体地势起伏较大，为典型的山岭微丘区地形二级公路，但由于选线合理，沿着山谷走向，因此路段经过的地区较为平坦。公路全长2.5km ,由于地形的限制，设计时速为40km/h。路面宽7m，路基宽8.5m，路面两侧为0.75m的土路肩。
本次设计分别对此公路段进行了几何设计和结构设计。在公路几何设计中，分别进行了平面、纵断面、横断面设计。本段路线平曲线共有交点5个，平均每公里约
1.43个，曲线半径最小为100m，最小缓和曲线采用40m，没有采用极限平曲线半
径。公路没有设置S型曲线，都是简单曲线。路线最大纵坡为0.809%，在公路结构设计中，分别进行了路基路面设计、涵洞设计、防护工程设计。经过交通分析，路面形式采用混凝土路面。垫层为15cm厚的天然沙砾，基层为15cm厚水泥稳定碎石，面层为24cm厚水泥混凝土；本段公路设计了4个涵洞。防护工程按工程需要，只包括护坡设计。
除了几何设计和结构设计外，还进行了工程量的计算，并进行了施工图预算。

Abstract
The graduation project for the ShaoXin road of the Contract Section-- A5 (K31 +600- K35 +100 section) construction design.
The road through the region more generally, is a typical mountain terrain-Hill District secondary road. But the alignment is reasonable, go along the valley and river, therefore road through the area more smooth. Road length 3.5 km, the design speed of 40 km / h. Road-7 m, roadbed width 8.5 m, on both sides of the road for 0.75 m of soil shoulder.
The design of this secondary road construction were a geometric design of the structure and design. In the geometric design of roads, respectively, were flat, vertical section, cross-sectional design. The curve of the road-a total of 5 intersection, with an average of about 1.43per km, the minimum radius of 100m, the smallest ease of use of 40 m, without a limit-radius curves. Highway S-curve has set up two, does not set a simple curve. Line of the largest Zongpo 0.809%。The structural design of the road, conducted embankment road design, the culvert design, engineering design protection. After traffic analysis, the form of concrete road surface. 15 cm thick cushion for the natural gravel, grass-roots level to 15 cm thick cement stabilized gravel, surface to 24 cm thick cement concrete; this paragraph 3 highway design culvert, in the form of two. According to the needs of Engineering ,the project of protection just including the slope protection design.

In addition to the geometric design and structural design, but also for the calculation of the project, construction plans and the budget.
Key words: Secondary roads; geometric design, structural design, engineering calculations, construction budget plans
