摘 要
本设计的题目是207国道张家口阳原段的设计,该公路为分向、分车道按需要控制出入的汽车专用公路.按一级公路标准设计,设计车速为80km/h.
该工程沿线土质含水量大,周围湿地、水田较多,另外有几处鱼塘和水池,土质为粉质中液限粘土,淤泥质粘土,时有软塑——流动状态,沿线地形变化较大.该地段属于季节性冻区,冻深1.0——1.5m.
根据路网最新规划,预计日使用初期2008年,双车道交通量为3300辆/日,车辆增长率8%,各种车辆按规范标准折合成小型车进行交通量的计算.
该设计主要从平面设计,纵断面的设计,横断面的设计,路面及线形的设计,重力式土挡土墙,加筋挡土墙,交叉口以及工程量统计等几方面进行设计和计算.
本设计中,严格按照一级公路的规范标准设计,在路线的选择上力求结合实地情况进行最优选取.在设计所选路线时,充分考虑到安全、经济、美观的三重意义,力求结构可靠,经济合理,质量优越,安全实用.尤其在平面线型的设计中,为了乘客及驾驶员的行车舒适和驾驶员在驾驶过程中不出现疲惫困乏之感,而精心设计了平面线形的组合与衔接,以达到车,人与周围环境有机地联系.在平纵面设计时,还考虑了平纵曲线线型的想结合,使行车更舒适,视觉更良好.设计的最终是达到一个安全、快速、经济、便利、舒适、美观的目的,为祖国的发展做出贡献.

The design is the subject of State Road 207 Zhangjiakou yang of the original design of the highway for hours to, - lane by the need to control access of vehicles dedicated highway. According to a highway standard design, design speed of 80 km / h. The project along the soil water content, surrounding wetlands, a field more than the other, there are several ponds and reservoirs. silty soil of Liquid clay, silt clay, are soft plastic -- mobile state, the topography changes along larger. The site is owned by a seasonally cold, deep freeze 1.0 -- 1.5 m. According to the latest road network planning, is expected to use the early days in 2008, the two-lane traffic for the 3300 / day, 8% growth in the number of vehicles, according to various standards for vehicles converted into small truck traffic calculations. The design major from graphic design, the profile design, the cross-sectional design, road alignment and design, gravity retaining wall. reinforced retaining walls, intersection and engineering output statistics in several areas, the design and calculation. The design, according to a strict standards for highway design, in the choice of routes sought to combine the field of optimal selection. In the design of the selected routes, taking fully into account the security, economic, aesthetic triple significance, seek to structure reliable and economically reasonable. superior quality, safe and practical. Particularly in the design of planar linear, To passengers and the driver's lane comfortable and the driver in driving the process there is no sense looking exhausted, carefully designed planar linear combination of convergence and to achieve the cars, people and the surrounding environment are organically linked. Ping in longitudinal design, but also to consider the longitudinal curve for the combination to make travel more comfortable, better vision. The ultimate design is to achieve a safe, rapid, economic, convenient, comfortable and beautiful purpose and to the motherland's development.
