摘要本次设计为沪宁高速公路沂淮江段初步设计。主要设计内容包括：(1)路线设计：平曲线设计、纵断面设计、横断面设计。(2)路基路面设计
此公路全长3265.975m，公路等级为高速公路，设计年限为15年，设计车速为120km/h，行车道宽度为39m，路基宽度为42m，有中央分隔带。
在本设计中主要完成的任务有以下几个方面:
首先进行了路线方案的比选，在两条线路中选出了线形好，造价低的路线，然后确定路线等级及其技术标准，在平面线形设计中，确定2个交点，其中平曲线的半径为600米。竖曲线共有2个变坡点。纵断面上坡度为1.574%。在确定路中线各点高程后，进行路线纵断面设计。纵断面设计主要根据路线的排水要求和最大、最小纵坡和坡长要求进行拉坡设计和竖曲线要素计算。最后，根据路基排水设计、路线超高计算绘制横断面图。由横断面设计计算出各段土石方的填挖数量，对各段进行土石方调配。整个公路线形美观，行车舒适。50944

Abstract The design for the preliminary design of the Huai River Shanghai-Nanjing expressway. The main design content includes: (1) route design: the plane curve design, vertical section design, cross section design. (2) design of subgrade and pavement
This road is 3265.975 meters in length, the highway grade highway, the design life of 15 years, the design speed of 120km\/h, lane width of 39 metres, subgrade width of 42 meters, a central separate belt.
Mainly in the completion of the task of design are as follows:
Firstly, compare and select the route plan, in two lines from linear, low cost route, and then determine the road grade and technical standards, in the plane alignment design, determine the 2 point, the horizontal curve radius of 600 meters. Vertical curve of a total of 2 slope changing points. Longitudinal slope of 1.574%. In determining the height of each point of the road center line, route vertical section design. Longitudinal section design is mainly based on the requirements of the road drainage and maximum, minimum longitudinal slope and slope length requirements for pulling slope design and vertical curve essential factor computation. Finally, according to the subgrade drainage design, route superelevation calculation and drawing section. The calculated earthwork excavation quantity by the cross-sectional design, for the earth-rock work allocation of each segment. The highway alignment is beautiful, comfortable driving.
Keywords: longitudinal section; cross section; subgrade; pavement
