摘要

摘要:本文主要研究地下开挖地铁在施工过程中对地面交通安全的影响,这是困扰城市交通管理者的一个严重问题。在地下施工中,由于隐蔽地下施工引起的地表沉陷和道路塌陷不断发生,造成人员伤亡和财产损失,严重影响城市道路的正常交通。城市道路管理者迫切需要一种快速、客观、易用的方法对此类风险进行预警和预防。因此,本研究整理了近20年来中国发生的相关事故案例,通过对自然因素、工程地质、结构类型和工艺类型的详细研究,总结了隐蔽地下工程对地面道路通行能力的影响机制。提出了两个指标Rank()和Rank()来描述隐蔽地下工程对地面交通通行能力的影响,采用综合学习方法建立了基于隐蔽地下工程对城市道路通行能力影响数据的预警方法,并在实际工程中得到了很好的应用。本研究结果对于帮助城市管理者快速评估城市道路交通风险具有重要意义。

Research on the impact of underground excavation metro on surface traffic safety and assessment method
ABSTRACT This study focuses on a problem that has been seriously troubled urban traffic managers: the impact of underground excavation metros on surface traffic safety during construction. In underground construction, surface subsidence and road collapse due to concealed underground construction constantly occur, resulting in casualties property damage and seriously impairing normal urban road traffic. Urban road managers urgently need a quick, objective, and easy-to-use method for the early warning and prevention of such risks. Therefore, this study collates relevant accident cases that have occurred in China over the last 20 years and summarises the impact mechanisms of concealed underground works affecting surface road traffic capacity through a detailed study of natural factors, engineering geology, types of structures, and types of workmanship. Two indices, Rank( ) and , are proposed to describe the impact of concealed underground works on surface traffic capacity, while an early warning method based on data on the impact of urban road capacity by concealed underground works is established using integrated learning methods and is well applied in practical projects. The results of this study are important for helping city managers quickly assess urban road traffic risks.
