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.
