毕业设计中文摘要
题 目（浦南公路设计） 摘要：本设计为福建一段山岭重丘区二级公路常规设计。 设计中，首先根据交通量确定道路等级，然后在1:2000地形图上确定两条备选路线，分别进行平面设计，纵断面设计，横断面设计，桥涵设置，最后对所定路线进行方案比选，从中选择最佳方案。从确定方案中进行设计，前期工作较初步设计更具体化，此外还对路基，路面，排水，涵洞进行了详细设计，对工程预算进行了简略编制。 关键词：交通量；道路等级；平曲线；竖曲线；排水；路基；沥青路面；预算； 1

Title PuNan highway design Abstract This design for a class of fujian mountains authors conventional design highway. According to the design of road traffic, firstly, and then determine the level at 1:2000 topographic map two alternative routes, determined separately, longitudinal design, graphic design, construction, cross-sectional design on the route to set, and select the best scheme. From design scheme, the prophase work is more specific, preliminary design of subgrade pavement in addition, drainage culverts, and makes a detailed design, project budget compiled the brief. Keywords： Traffic, Road level, Flat curve, Vertical curve, Drainage, Roadbed, Asphalt pavement, Budget 1
