沈阳建筑大学毕业设计（论文） PAGE 1 PAGE 8 摘 要 根据设计任务书提供的设计资料和设计要求以及部颁标准和规范对昌图之调兵山二级公路K0+000～K4+579.918段进行了路基路面综合设计。设计车速为80km/h ，双向二车道。 主要内容包括：路线平面设计、路线纵断面设计、路基横断面设计、路基路面排水设计、路面结构设计、小桥设计、施工组织设计以及概预算的编制等。在平面设计中，在设计线路上选了四个交点，曲线半径分别为500m，600m, 300m, 370m。在纵断面设计中，全线共设六个变坡点，竖曲线半径分别为12500米，10000米，3800米，112100米, 10000米，3400米。在小桥涵设计中，设计内容是一座跨径为18米的钢筋混凝土T型梁桥，主要进行了桥梁上部结构的计算和验算。另外还有施工组织设计和概预算等相关内容。 通过本次毕业设计，在专业知识方面得到了综合训练和提高，增强了独立分析和解决问题的能力，取得了很好的效果。 关键词： 二级公路；路基；路面；综合设计 Abstract According to the technical standards and specifications for highway design published by the Ministry of Communications of China, the comprehensive design of highway subgrade and pavement from K0+000 to K4+579.918has been carried out based on the data of Changtu-Diaobingshan secondary roads in Liaoning Province. The designed vehicle speed is 80km/h , bidirectional two traffic lanes. The main contents of the design included highway line of graphic design, vertical alignment design, line cross-sectional design, subgrade and pavement drainage, pavement structure design, the design of small bridges, construction design, and the preparation of budget estimate, ect. In the plane design, considered is the mountainous terrain area newly built road, I have chosen four points of intersection on the Lines in the design roads, the point of intersection radius respectively is 500m, 600m, 300m, 370m,. In the profile section design, the entire line has six to change the slope spot, the radius respectively is 12500m, 10000m, 3800m, 112100m, 10000m，3400m. The small arch of bridge design has mainly carried on the bridge structure computation and checking computations. Design is a 18 meters of reinforced concrete T-beam bridge. In addition, it has the related content of the construction organization plan and budgets and so on . During this graduation design, the expertise is a comprehensive training, and the ability of independent analysis and solving problems were improved and strengthened, so good effects have been achieved.
