北京市东四环（双新桥路段）改造工程施工期间交通组织研究

Study on Traffic Organization during Reconstruction of Beijing East Fourth Ring Road (Shuangxin Bridge Section) Project

摘要:

东四环是北京市东部区域重要的快速干道，与区域内多条东西向高快速路连接。高铁北京朝阳站2021年开通后，双新桥及周边道路出现常发性交通拥堵，亟须对东四环进行拓宽改造。本次改造含东四环双新桥菱形立交建设、主路650 m竖向抬高改造及辅路4.5 km拓宽，受交通饱和、现况管线多、施工复杂等因素制约，导改分5期实施。工程面临交通超饱和、专业多样、管线改移受限等难点，遵循“占一还一”原则，完善交通安全设施，分区段分步施工，保障现况通行与施工同步。改造及交通组织方案可为同类工程提供参考。

Abstract:

The East Fourth Ring Road is a major express arterial road in the eastern Beijing, connecting multiple east-west expressways and arterial roads in the region. Since the opening of Beijing Chaoyang High-speed Railway Station in 2021, the Shuangxin Bridge and its surrounding roads have experienced recurrent traffic congestion, making it urgent to widen and reconstruct the East Fourth Ring Road. This reconstruction project includes the construction of a diamond interchange at Shuangxin Bridge on the East Fourth Ring Road, the vertical elevation of the main road over a length of 650 m, and the widening of auxiliary roads over 4.5 km. Constrained by saturated traffic, numerous existing pipelines and construction complexity, the traffic diversion is implemented in five phases. The project faces challenges such as oversaturated traffic, diverse engineering specialties, and limited pipeline relocation capacity. Following the "occupy one, replace one" principle, traffic safety facilities are improved, and construction is carried out section by section and step by step, ensuring that existing traffic flows are maintained concurrently with construction activities. The reconstruction and traffic organization schemes can provide a reference for similar projects.
