Research On Security Risk Management Of Subway Construction Site

In recent years, the safety questions of subway construction process are very prominent both at home and abroad, and its frequent security incidents occurred at the construction site, the research on the subway construction site security risk management is imperative.In this paper, take the security risk of subway construction process as the research object, the concept of risk management will be the introduction of subway construction safety management, and start with the construction safety production management status and subway safety management problems, and research on the occurrence mechanism of the construction site, risk identification and evaluation of methods, to establishe a model of risk management and risk assessment in construction site.Construction of the existing safety management experience in the traditional type-based, not on the security level of risk identification and control. In this paper, a comparative study of qualitative analysis and quantitative analysis, empirical research and theoretical study of the combination of methods. Checklist of safety improvement, risk analysis will be pre-evaluation form used in safety inspections, security checks clear the table the weight of the subsystem value; to security risk analysis of risk factors, the evaluation focuses on LEC and its parameters correction method for grading the risk of sources;From the security and occupational health system, a major accident hazards and risk control and emergency response mechanisms and contingency plans, etc. on all aspects of construction site safety management of risk control measures, by applying the PDCA method of risk management for continuous improvement.Combination of Beijing Subway Line construction on the 4th example, from the safety management of the risk analysis, risk identification, risk assessment, risk control all aspects of the construction site on the implementation of a safety risk management of specific methods.
