摘要我的毕业设计的题目是世纪大道城市道路设计。设计路段桩号为K0+000至K2+310。585，全长2310。585米，设计车速为60km/h，路基宽度为25。5米。本次设计的内容主要有：路线选线方案比选、纵断面和横断面设计、路面设计，土石方计算和排水设计、交叉口设计。设计全程阅读了相关规范和文献资料。选线方面严格按照相关规范的规定进行，路线的线形适应地物地貌，适应周围环境；并且满足了汽车行驶动力学的要求和驾驶员和乘客视觉上的要求；路线线形满足相关规定的长度；并尽可能避免了大量拆迁，降低了工程的总体成本。纵断面设计中的高程满足市政规划的要求，与周围的自然环境和已有建筑物相适应，有利于排水系统的的设置；纵断面设计中要考虑的一个重要环节就是土石方的填挖与调配问题，还有车辆运输的效益问题，综合各个方面设定了纵断面的坡度值；交叉口的导流岛设计和排水设计也是本设计的重点内容。87381

Abstract My graduation project topic is Century Avenue Design of Urban Roads。 Design sections Stake K0 + 000 to K2 + 310。585, a total length of 2310。585 m and a design speed of 60km / h, the roadbed width of 25。5 meters。 The contents of the design are: Route Selection Alternatives, longitudinal and cross-sectional design, road design, earthwork calculations and drainage design, intersection design。 Read the full design specification and the relevant literature。 Selection in strict accordance with the relevant norms of conduct, the route alignment feature adaptation topography, adapt to the surrounding environment; and meet the requirements of cars with the requirements and dynamics of the driver and passengers visually; linear path length to meet the relevant provisions; and try to avoid a lot of demolition, reducing the overall cost of the project。 The elevation profile design to meet the requirements of urban planning, with the surrounding natural environment and adapt existing buildings, is conducive to the provision of drainage systems; profile design considerations is an important part of the cut and fill earthwork and deployment issue, there is the problem vehicle transport efficiency, integrated in all aspects of setting up the profile of the gradient value; intersection island design persion and drainage design is also the key elements of this design。

Keywords: urban trunk road; route line selection; pavement design; drainage design; intersection design。
