Safety Risk Analysis and Countermeasures of Railway Construction Road Safety Based on the Analytic Hierarchy Process
With the continuous expansion of the railway network,the safety of cross-road construction on the railway has become a key engineering problem.Based on the analytic hierarchy process(AHP),this paper systematically identifies,evaluates and sorts the various safety risk factors in the cross-road construction on the railway in order to provide scientific decision-making basis for the construction safety management.By constructing hierarchical model and judgment matrix,the relative importance of risk factors is quantified,and the reliability of the results is ensured by consistency test.The results show that structural risk and traffic risk are the major critical safety factors,which should be given priority attention.In order to reduce the potential safety hazard in construction process,the study also puts forward the corresponding risk prevention and control measures,including strengthening the design review,optimizing the construction monitoring and perfecting the emergency plan.
