1、 摘要 本设计为解决解放广场的交通问题在解放广场处设计环形立交，桥长 433m，环 形立交最高点的高程为海拔 150.4m。桥址沿解放大街跨立于整个解放广场。此地段 地形较平坦，而且线路比较顺直。 本设计遵循“适用，经济，安全，美观”的原则并充分考虑了解放广场的交通量、 通行能力、工程地质和各项技术标准。本设计主要完成以下内容：关于解放广场的交 通量、车速与通行能力的交通调查，以及对交通调查所得数据的处理与分析。立交方 案设计与匝道方案设计以及立交的平面图，纵断面图和横断面图的绘制与相关计算， 最后对立交附属设施进行了简单的介绍例如排水，照明和交通标线标志。 通过毕业设计的全过程，可以使专业知
2、识进一步提高。能够调查并分析交通量、车 速和通行能力，更好的掌握了施工图的平纵横图。进一步开阔了视野，为以后的工作 打下了结实的基础，希望可以将这些知识熟练的应用于以后的实际工程中。 关键词： 交通量交通量; ; 通行能力通行能力; ; 立交立交; ; 平面图平面图; ; 横断面横断面; ; 纵断面纵断面 Abstract This is designed to solve the traffic problem in jiefang Square jie fang Square office design ring overpass, bridge length 433m, the high
