公路与城市道路交叉的枢纽型匝道横断面技术标准选用探讨

Discussion on the Selection of Technical Standards for Hub Ramp Cross Section at the Intersection of Highway and Urban Road

结合公路与城市道路交叉的枢纽型互通匝道的技术要求,该文针对匝道横断面及加宽的选取,从不同的规范标准、工程规模等多方面进行了比对分析,并结合安全、养护等因素,阐述了匝道技术标准的选择思路。

Combining the technical requirements of the hub-type ramp connecting highway and urban road,the choice of cross-section type and widening are studied in this article.Different standards and project scales are considered in comparative analysis.Moreover,the idea of ramp technical standard choice is expounded based on several factors,such as safety,maintenance and so on.
