BIM技术在交通疏解方案中的应用研究

Research on Application of BIM Technology in Traffic Dredging Scheme

摘要: 在城市既有道路上的高架桥施工建设过程中，交通疏解是解决工程施工和保持交通的措施，它涉及道路交通车辆动态预测、高架桥施工措施及施工，是目前城市高架桥施工中亟待解决的复杂难题。本文通过某市城市高架桥施工阶段BIM技术应用实例，研究了BIM技术在高架桥的交通疏解过程中的应用点和流程，构建了基于BIM技术的交通疏解动态模型；通过分析BIM技术在交通疏解中解决实际施工场地布置和道路翻交等环节的具体应用，确定了BIM技术可应用于车流量模拟、优化施工场布方案、深化道路翻交和管线碰撞检查等关键应用点，为复杂环境中高架桥类似工程提供参考研究和借鉴。

Abstract: In the construction process of viaduct on existing roads in the city, traffic relief is a measure to solve the problem of engineering construction and maintain traffic. It involves dynamic prediction of road traffic vehicles, construction measures and construction of viaduct. It is a complicated problem which needs to be solved urgently in the construction of urban viaduct at present. This paper studies the application points and processes of BIM technology in the traffic dredging process of a city viaduct during the construction stage of a city viaduct, and constructs a dynamic model of traffic dredging solution based on BIM technology. By analyzing the concrete application of BIM technology in solving the problems of actual construction site arrangement and road turnover, it is confirmed that the application of BIM technology in vehicle flow simulation, optimization of construction site layout, deepening of road overturning and pipeline collision inspection and other key application points are determined, which provide reference research and reference for similar projects of viaduct in complex environment.
