独墅湖大道快速化改造工程总体设计方案

Overall Design Scheme of Dushuhu Urban Expressway Reconstruction Project

摘要:

以苏州市独墅湖大道快速化改造工程为依托，对该快速路建设的功能定位、服务对象、总体布置方案等进行概述，重点分析了独墅湖大道快速化总体敷设形式、出入口布置、建设规模等方案。该工程有两处重要立交转换节点，立交区范围内受到既有构筑物、管线、河道、高压电力线等多重因素限制。在满足节点交通功能的前提下，研究比选了多因素限制条件下的立交新建与改建方案，并确定了相应工程设计方案解决受限问题并实现立交功能，为今后复杂节点的立交建设方案提供参考。

Abstract:

Relying on the Suzhou Dushuhu Avenue Expressway Reconstruction Project, the overview of functional positioning, service targets and overall layout scheme of this expressway construction is provided, and the overall laying form, entrance and exit layout, and construction scale of the Dushuhu Avenue expressway are analyzed and explained in detail. There are two important interchange transfer nodes in the project, which are limited by multiple factors such as existing structures, pipelines, rivers and high-voltage lines. On the premise of meeting the node traffic functions, the construction and reconstruction schemes of the interchange under multiple limiting factors are studied and compared, and the relevant engineering design schemes are determined to solve the limitation problems and realize the interchange functions, which provides the reference for the interchange construction schemes in the complex nodes in the future.
