昆山市东城大道快速化改造工程总体设计

Overall Design of Kunshan Dongcheng Avenue Expressway Reconstruction Project

摘要:

东城大道是昆山“双环-四联-八射”快速路系统外环中东环的重要组成部分，对其进行快速化改造须开展总体方案设计研究。以功能需求分析为依托、交通量分析为支撑，梳理了沿线重要节点及控制物，特别针对两处现状隧道控制条件，提出了两个总体设计方案，并对方案进行了论证与比选。最后综合考虑现状隧道、沿线高压铁塔及重要出行节点等控制因素，确定了总体方案和出入口布置，效果良好。

Abstract:

Dongcheng Avenue is an important part of the outer ring in the "double-ring, four-link and eight-shoot" expressway system of Kunshan. The overall scheme of its expressway reconstruction is designed and studied. Relying on the functional demand analysis, based on the traffic flow analysis, the important nodes and controlling substances along the route are sorted out. Especially for the control conditions of two existing tunnels, two overall design schemes are proposed. And the schemes are demonstrated, compared and selected. Finally considering the control factors of old tunnels, steel high-voltage towers and important trip nodes, the overall design scheme and the entrance-exit layout are determined. The effect is good.
