车陂路北延线广园立交节点技术方案研究

Study on Technical Scheme of Guangyuan Interchange Node in Chepo Road North Extension Line

摘要:

车陂路北延线设计作为广州市天河区东部一条南北向贯通的主干道，建成之后可极大改善天河区东部南北向交通状况，促进区域交流及经济发展。广园立交节点作为工程中重要的控制节点，立交范围内有铁路、城市快速路、主干路、次干路等不同等级道路，还有多方向交通转换功能需求；方案设计时需综合分析各种影响因素，通过主线线形技术标准、立交主要交通功能、对现状道路及环境的影响、投资规模等方面对多方案进行比选，得出最优方案。广园立交节点设计可以为复杂城市立交设计提供一定的参考和借鉴意义。

Abstract:

As a main road running from south to north in the east of Tianhe District of Guanghou, Chepo Road North Extension Line can greatly improve the south-north traffic conditions in the east of Tianhe District after constructed so as to promote the area exchange and economic development. As the important control node of the project, there are the railways, urban expressways, main roads, secondary roads and different grades of road in the range of Guangyuan Interchange including the requirements of the multi-direction traffic transfer functions. It is necessary to comprehensively analyze various influencing factors during the scheme design. Many schemes are compared through the alignment technical standards of the main line, the main traffic functions of interchange, the influences on the current roads and environment, and the investment scales in order to achieve the best scheme. The design of Guangyuan Interchange Node can provide the certain reference for the design of the complicated urban interchanges.
