摘要
本设计为从新兴屯到李家店的一段山岭重丘区二级公路常规设计，分为初步设计和详细设计两个步骤。
初步设计中，首先根据交通量确定道路等级，然后在1:10000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。
详细设计从确定方案中选取3.8Km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，重点是建筑安装费的计算。

Abstract
This design is a general one that is about a road of second grad from Xinxingtun to Lijiadian in the mountainous area, which is made up of primary design and detailed design.
In the primary design process, first of all, we should determine the road-grade according to the traffic volume, then, two spare routes are determined in the terrain map with a scale of 1:1000, including the plane design, the vertical section design, the transect design，the setting of the bridges and culverts. At last, there is a compare between the two projects and the better will be adopted.
In the detailed design process, about 3.8 kilometers is selected from the projects determined. The prime task is more concretely than the primary design. Furthermore, subgrade, pavement and drainage, the bridges and culverts have been designed in stress as well. Besides, the project budgetiscompile simply, which is mostly about the account of the architectural and installing cost. Keywords traffic volume, road-grade, horizontal curve, vertical curve, drainage,
subgrade, asphalt pavement, budget supervision
