互通立交匝道连接部几种纵坡接线方法的对比研究

Comparative Study on Several Longitudinal Slope Connection Methods of Interchange Ramp Connection

互通立交设计是一个综合性的系统工作,数据繁琐、计算量大,在满足国家规范标准的同时,还需综合考虑地形条件、征收状况、交通流量、立交选型、附属设施及细部衔接等问题。匝道连接部纵坡接线设计是互通立交中的重要环节,实际工作中,设计人员的接线方式较为多样。通过近几年的互通立交设计工作,结合具体实例,对这一环节多种接线方式进行归纳总结和对比研究,分析优缺点,供广大立交设计人员参考。

Interchange design is a comprehensive & systematic work, with cumbersome data and large amount of calculation.While meeting the national standards, it is necessary to take into account the topographic conditions, levy conditions, traffic flow, type selection of interchanges, ancillary facilities and detailed linkages. Longitudinal slope wiring design of ramp junction is an important link in interchange.In practical work, the wiring methods of designers are more diverse. Through the interchange design work in recent years, combined with specific examples, this paper summarizes and compares various connection modes in this link, and analyses the advantages and disadvantages for the reference of interchange designers.
