Research On Risk Management Of Construction Safety Of Large Railway Maintenance Machinery

With the rapid development of China's railway transportation services,the railway mileage is increasing.Large Railway Maintenance Machinery has a significant advantage in operating efficiency,accuracy and degree of automation,so that it is widely used in Railway Maintenance.Large Railway Maintenance Machinery construction crew workers have more job time constraints,construction methods and more complex construction environment and other characteristics,and therefore more safety risk factors exist in the construction job.If security incidents occur,it will directly affect the normal transport order and traffic safety of the railway line,and even cause serious economic losses and adverse social impact.Therefore,to study Large Railway Maintenance Machinery security risk management of construction,can control the security risks in the process of construction and ensure the construction safety is of great significance.This study summarizes the research status and development trend of domestic and foreign security risk management.Analysis of the current Large Railway Maintenance Machinery construction tasks,the equipment failure and production area of construction to hazards identification,etc.At the same time,the establishment of Large Railway Maintenance Machinery construction safety risk assessment model,using the Risk Matrix security risk comprehensive assessment of the probability and consequences of security risk to quantify,obtain a security risk weights and risk level.From the establishment construction safety management organization,preparation of construction safety management standards and measures and the implementation of safety risk monitoring and early warning is given Large Railway Maintenance Machinery construction coping mechanisms security risk management.Which can provide a theoretical guarantee security for enterprises to improve risk management and reduce construction accidents.
