Abstract:Research purposes: The damage to the adjacent buildings caused by metro construction and its prevention attract more attention nowadays. Aiming at the impact of the metro construction on the adjacent bridge,this paper analyzes the safety risk management process in construction of metro adjacent to bridge and presents a complete set of the risk management system for providing the scientific and effective reference to the adjacent bridge with the different risk levels.
Research conclusions: Taking the form and depth of the foundation and the relation between the bridge pile and the spatial location of metro into account,the adjacent grade of the bridge to metro can be divided into 5 levels. The present bearing capacity of the adjacent bridge can be assessed by checking and diagnosing the current appearance,working state and dynamics characteristics of the bridge structure. Based on both of the adjacent grade and reliability evaluation results,the safety risk of adjacent bridges to metro construction can be classified into the 4 levels: Ⅳ,Ⅲ,ⅡandⅠ.For the different safety risk levels,the corresponding measures should be taken. It has been applied in construction of the Wuhan metro adjacent to bridge,obtaining good result.
