Abstract <br><br>This graduation design is a secondary road design and cement concrete pavement design for the Qi River section from Dezhou to Jinan. The road topography is located in the plain area with a few hills. Based on the principles of safety, economy and beauty, the farmland should be occupied as little as possible. Favorable terrain wiring, harmonizing the highway route with the natural landscape, and designing the road section for the purpose of making full use of old road reconstruction and reducing project investment. <br>The design of the second-class highway from Dezhou to Jinan was carried out in accordance with the design specifications under the influence of the terrain, geology, climate and environment of this area. The grade of the highway is Grade II, the design speed is 60km / h, the total length of the highway is 4000m, the width of the subgrade is 10m, and the width of the traffic lane is 3.5m, and the earth shoulder and the hard shoulder are both 0.75m left. <br>The contents of this design include: flat design, vertical section design, cross section design, roadbed design, plane line design including paper line selection, alignment, circular curve, transition curve setting, straight line design, etc .; vertical section design includes drawing Slope and vertical curve design, etc. When designing the vertical curve, attention should be paid to the problem of line-of-sight and line-of-sight guidance, that is, to meet the "horizontal length"; when designing the cross section, the driving is more comfortable. Designed side ditch and drainage ditch. <br>Keywords: graphic design; secondary highway; pavement design

Summary<br><br>This graduation design for the Texas to Jinan Qi River section of the secondary highway design and cement concrete pavement design, road terrain is located in the plain area, slightly less hills, in line with the principle of safety, economy, beauty, as little as possible to occupy farmland, the use of favorable terrain wiring, so that the road route and natural landscape coordination and unity, and to make full use of the old road reconstruction to reduce the investment in the project for the purpose of designing the road section.<br>The design of the second-level highway from Texas to Jinan is carried out according to the design specifications under the influence of the terrain, geology, climate and environment of this area. The highway grade is a secondary highway, designed to speed 60km/h, the highway length of 4000 m, the width of the road bed is 10m, of which the lane width of 3.5m, of which the dirt shoulder and hard road shoulder are left 0.75m.<br>The contents of this design are: graphic design, profile design, cross-sectional design, road-based design, flat line design includes paper selection, alignment, circular curve, ease curve setting, straight line design, etc. ;<br>Keywords: graphic design; secondary highway; road design

abstract<br>The graduation design is the design of the second-class highway from Dezhou to Jinan and the design of cement concrete pavement. The terrain of the highway is located in the plain area, with a little hills. Based on the principle of safety, economy and beauty, the farmland is occupied as little as possible, and the favorable terrain is used for wiring, so as to coordinate and unify the highway route and the natural landscape, and the purpose is to make full use of the old road reconstruction and reduce the project investment Segment.<br>The design of Dezhou Jinan secondary highway is carried out in accordance with the design specifications under the influence of topography, geology, climate and environment in this area. The highway is a class II Highway, with a design speed of 60km / h, a total length of 4000m, a subgrade width of 10m, in which the lane width is 3.5m, and the earth shoulder and hard shoulder are 0.75m to the left.<br>The contents of this design include: plane design, vertical section design, cross section design, subgrade design, plane line design, including paper line selection, alignment, circular curve, transition curve setting, straight line design, etc.; vertical section design, including slope vertical curve design, etc.; in vertical curve design, attention should be paid to the problem of driving sight distance and sight line guidance, which meets the requirement of "horizontal package vertical"; in cross section design, attention should be paid to the problem of driving sight distance and sight line guidance In order to ensure the service life of the road, side ditch design and drainage ditch design are also made on the road section.<br>Key words: graphic design; secondary highway; pavement design<br>
