摘要
通过分析综合交通枢纽接驳高架匝道的交通运行特性,阐述了其使用功能及交通组织思路,提出了设计标准选取的建议。高架落客平台是其关键设计技术之一,对高架落客平台的车道组成、长度计算方法以实例进行了解析。最后,对高架匝道设计过程中常遇到的引道坡脚至平交口距离、车道数选择、上部结构型式选取等问题进行了探讨,并提出相应的设计方法。
According to the analysis on the traffic running characteristics of connecting the comprehensive traffic hub and viaduct ramp, the article sets forth its use function and traffic organization idea, and puts forward the proposal to select the design standards. The elevated pedestrian platform is one of its key design technologies. The article analyzes the lane composition and length calculation method of elevated pedestrian platform by the practical cases, and finally discusses the issues of the distance from the approach ramp toe to the grade intersection, the selection of lane number and the selection of superstructure style commonly met in the design of viaduct ramp, and puts forward the relative design methods.
