毕设基本摘要
摘要
交通运输事业是国民经济的重要组成部分，是国民经济的命脉，是联系工业和农业、城市和乡村、生产和消费的纽带。它在国家的政治、经济、军事、文化建设中具有重要作用。本设计是平原微丘区高速公路的方案设计。地形起伏较大，设计车速为100km/h，路基宽度26m。通过调查研究和分析讨论，掌握所设计课题的有关结构构造、使用功能及质量要求。设计分为五部分，第一步是路线方案设计，第一步是公路路线设计，通过两个方案的比选来确定最佳路线；第二步是路线设计，其中包括:平面设计、纵断面设计、横断面设计;第三步是公路路基设计，包括:路基设计和重力式档土墙设计;第四步是沥青混凝土路面设计；第五步是排水系统设计，其中包括路基排水和路面排水设计。本设计路段总里程为4.764公里，平面设计内设3个交点，两个基本型平面曲线反向。

Abstract
Transportation business is an important part of the national economy, is the lifeblood of the national economy, are linked to industry and agriculture, city and village, production and consumption of the link. It in the country's political, economic, military, and culture plays an important role in the construction of. This design is the high plains area highway micro scheme design. Terrain ups and downs is bigger, the design of the speed to 100 km/h, roadbed width 26 m. Through the investigation and analysis of the discussion, the relevant design task master structure, function and quality requirements. Design is divided into five parts, the first step is to route design, the first step is highway route design, through the two scheme than the election to determine the optimal route; The second step is to route design, including: graphic design, longitudinal design, cross-sectional design; The third step is to highway roadbed design, including: roadbed design and gravity file wall design; Step 4 is the asphalt concrete pavement design; Step 5 is drainage system design, including the roadbed drainage and the design of pavement drainage. This design section 4.764 km total mileage, graphic design with three intersect, two basic plane curve reverse.
