既有高速公路增设服务型立交要素分析——以S32高速昆阳路立交工程为例

在城市快速化发展背景下，已建高速路网结构体系已逐步处于城区范围，既有高速公路立交出入口间距过大与沿线区域快速进出高速路网的迫切需求的矛盾与日俱增。以S32申嘉湖高速昆阳路立交工程为例，从增设高速服务立交项目选址与立交选型分析、交通影响特征分析、新材料合理应用等相关要素，总结出既有高速公路增设服务型立交收费匝道总体方案设计技术特点，提出了合理应用新型材料解决收费系统与路面结构层电磁干扰影响设计思路，旨在为后续城区高速公路增设服务型立交出入口提供技术借鉴和指导。

Analysis on Factors of Adding Service Interchange in Existing Expressway for S32

Under the background of rapid urban development, the built expressway network structure system has gradually been in the urban area. There is an increasing contradiction between the large distance between the entrance and exit of the existing expressway interchange and the urgent need for quick access to the expressway network. Taking Kunyang Road Interchange Project in S32 Shanghai-Jiaxing-Huzhou Expressway as an example, the technical characteristics of the overall scheme design for adding the service interchange toll ramp of the existing urban expressway are summarized from the addition of expressway service interchange project location and interchange selection analysis, traffic impact characteristics analysis, reasonable application of new materials and other related factors. The design idea of using new materials reasonably to solve the electromagnetic interference of toll collection system and pavement structure layer is put forward in order to provide the technical reference and guidance for the subsequent addition of service interchange entrances and exits on urban expressways.
