沈阳建筑二级公路 毕业设计 .doc

摘 要 根据已有的设计资料和中国交通部设计要求以及部颁标准和规范，K0+000~K4+820.041段进行了路基路面综合设计。 km/h，双向车道。 考虑到是区新建公路，在路上选了个交点，半径300m，m，m，m，900m，缓和曲线长度为130m，90m，100m，150m，均符合规范要求。纵断面设计全线共设个变坡点，半径分别为000m，00m，000m，7000m，20000m。小桥涵设计主要进行了上部结构的计算和验算。 本设计部分图纸采用CAD系统绘制，部分数据采用Excel表格计算显示。此次设计使我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，取得了良好的效果。 关键词： 二级公路；路基；路面；排水设计；桥梁设计；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+820.041 has been carried out based on the data of Dalian-Zhuanghe secondary roads in Liaoning Province. The designed vehicle speed is 60km/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 five points of intersection on the Lines in the design roads，the point of intersection radius respectively is 300m，250m，300m，500m，900m.Mollifying the curve length is 130m，90m，100 m， 150m，150m. In the profile section design， the entire line has five to change the slope spot，the radius respectively is15000m，8000m，15000m，7000m，20000m. The cross-sectional design one kilometer route as the design object ，a cross-sectional diagram of every 20 meters，the slope gradient of 1:1.5.In the design of bridges and culverts ，the main of the calculation and checking the upper structure of a bridge of 17 meters.Using manual and procedure of the method of combining the pavement structure design in accordance with the regulations. According to road construction ，the construction organization design of construction personnel, construction machinery and engineering quantity arrangement etc.Moreover still use to toget
