Design of Overall Scheme for Huayuan Avenue Tunnel in Hefei

摘要:

以花园大道隧道工程总体设计为例，通过对区域路网规划解析，分析花园大道交通功能，论证项目建设的必要性。总体设计公园总体规划的要求和现状建设条件，意在探求在城市隧道设计在线形及洞口位置、隧道进出匝道布设、双层立交隧道、“管幕+顶进”工艺的构思理念，为以后类似项目提供借鉴。

Abstract:

Taking the overall design of Huayuan Avenue Tunnel Project as an example, and by planning and analyzing the regional road network, the traffic function of Huayuan Avenue is analyzed and the necessity of the project construction is demonstrated. Combining the requirements of overall park planning and the current construction conditions, it is intended to explore the conception and idea of urban tunnel design in the alignment and portal location, tunnel on/off ramp layout, double-deck overpass tunnel, and "pipe curtain + jacking" process so as to provide the reference for the similar projects in the future.
