高速公路出入口改建关键技术研究

Research on Key Technologies for Reconstruction Scheme of Expressway Entrance and Exit

高速公路出入口互通立交改建是一项复杂的系统工程。受现状互通设施、有轨电车、高压走廊、河道水系、慢行系统等条件限制,互通立交改建难度较大,是高速公路出入口改建的重点和难点。为实现设计目标需要进行关键技术研究。以苏州绕城高速天池山互通改建为例,从优选互通型式、桥型选择、以人为本设计、宽容设计、精细化设计、绿色设计理念等方面进行探讨,以期为同类型项目提供参考和借鉴。

The reconstruction of interchange at the entrance and exit of expressway is a complex and systematic programme.Due to the limitations of the existing interchange facilities,trams,high-voltage corridors,river water systems,slow traffic systems and other conditions,it is difficult to reconstruct the interchange,which is the key and difficult point in the reconstruction of expressway entrances and exits.In order to achieve the design goal,it is necessary to carry out studies of key technology.In the paper,taking the reconstruction of Tianchishan Interchange of Suzhou Ring Expressway as an example,the optimization of interchange type,bridge type selection,people-oriented design,tolerant design,refined design,and green design concept are discussed,which can be used as reference for the selection and design of similar projects.
