某高速公路枢纽互通式立体交叉优化设计分析

Optimization Design Analysis of Interchange at an Expressway Hub

枢纽互通式立体交叉是高等级公路实现交通转换的重要组成结构之一。由于枢纽互通式立体交叉的交通流向、节点转换、结构形式的多样性,一般占用土地空间较大,施工组织较一般互通式立体交叉、主线工程更为繁琐复杂。文章结合技术指标、工程规模和施工组织,对某高速公路枢纽互通设计进行优化调整,总结设计经验,可有效降低工程费用,减少土地占用,为周边居民创造良好的通行环境。

Hub interchange is one of the important components of achieving the traffic conversion of high-grade highways.Due to the diversity of traffic flow,node conversion,and structural form in hub interchange,it generally occupies a large amount of land space,and the construction organization is more complex and cumbersome than that of the general interchange and mainline project.The technical indicators,project scale and construction organization are combined to optimize and adjust the design of an expressway hub interchange.The design experience is summarized,so as to effectively reduce the project cost,reduce the land occupation,and create a good traffic environment for surrounding residents.
