Research on Constructing Dual Prevention Mechanisms in Urban Rail Transit Projects
The construction of dual prevention mechanisms is an important task in the safety management of urban rail transit projects.Currently,guidance in the construction of dual prevention mechanisms is deficient owing to the lack of laws and regulations,differences in the understanding and implementation of dual prevention mechanisms in various cities,and various problems in the execution process.An investigation of the current scenario of the construction of the dual prevention mechanisms revealed that the problems are primarily manifested in the mixing of phrases and terminologies,lack of safety risk management assessments,incomplete investigation and rectification of hidden dangers,inconsistent grading standards of hidden dangers,and insufficient combinations of risk and hidden danger controls.Relevant research can provide a reference for the standardization and improvement of dual prevention and control in the field of urban rail transit engineering.
