文档介绍：高速公路A3标段高速公路施工图设计
摘要
现如今,随着我国经济的迅猛发展,普通的交通运输已经不能满足日益发展的经济的需要,因此,高速公路应运而生,为交通运输的发展提供了新的方向。
本设计为辽宁地区某高速公路A3标段高速公路施工图设计。该地位于辽宁省中东部的平原微丘区,。设计内容包括:选线与定线是根据交通量确定道路等级,在地形图上确定三条备选路线,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;平面设计按照书中要求选定路线的各种技术指标,计算平曲线参数,确定线形;纵断面设计主要考虑纵坡在满足书中和规范上各规定的情况下,尽量使填挖趋于平衡,利于排水和行车舒适,计算竖曲线要素;横断面设计中考虑排水和行车安全稳定等因素确定道路的横断面形式;路基设计主要进行确定压实标准、路基高度、边坡形状、坡度、路基排水等设计;路面结构设计主要进行路面结构设计和验算;排水设计要根据实际地形条件进行排水设施的设计;施工组织设计根据工程实际情况,对整个施工过程、各个环节、步骤进行详细的组织设计;概预算的工作是对工程的造价进行估算以了解工程的总价值。
本设计是我们对理论知识的直接运用,是理论联系实践的重要体现。

Abstract
Nowadays,with the rapid development of Chinese economy,the transportation has been unable to meet the growing needs of the economy,therefore,the highway transportation development emerge as the times require,in order to provide a new direction.
The design is a new built highway on plain in Liaoning of A3, the region is in Liaoning Province of china, this regional topography is the plain. The total length of the highway is contens of the design includes:Graphic design in accordance with the requirement of the selected book of the various technical indicators line, calculated curve parameters, determine the line;Vertical-design mainly consider according to the books and norms,to cut to fill balance, considering drainage and fort, and calculated vertical curve elements;Cross-sectional design considerate the drainage traffic safety and other factors to determine the form of the road;Roadbed design mainly carries on side ascent shape choice、grade design、 roadbed drainage design;Road design mainly carries on pavement structure level design and checking calculation;The design of the drainage conditions in accordance with the actual topography of the design of drainage facilities;anization design based on the actual situation in the project for the entire construction process, the various segments of the steps anizational design;
The budgetary work is the valua which builds engineeri
