Research On Risk Assessment And Control Technology Of Hazardous Materials Transportation In JiaShao Bridge

Most of the transportation of hazardous materials is long distance transportation mode in our country,the transportation of hazardous materials can save the economy and time cost through the cross sea bridge,and have a significant social and economic benefits,but in china there is no mature experience about the cross sea bridge transportation of hazardous materials risk assessment and control of the management of technology,the corresponding safeguard measures are relatively weak.Jiashao bridge is another bridge across the Gulf of Hangzhou after Hangzhou Bay Bridge,the complex weather conditions,the bridge structure and the special cross regional management lead a more strict requirements about transportation of hazardous materials,to carry out specific research on the transportation of hazardous materials risk assessment and control technology means a lot for the safety management of hazardous materials transportation and safe operation of the sea cross bridge.Through the comprehensive analysis of hazardous materials transportation accident causes and mechanism,make the general road transportation risk theory applied to the risk analysis of dangerous goods transportation and explore the theoretical basis of road transportation of hazardous materials transportation safety risk,establish the safety risk assessment index system of hazardous materials transportation in Jiashao bridge combined with the actual situation,determine the hazardous materials transportation safety risk evaluation criteria;use fuzzy comprehensive evaluation method for the transportation of hazardous materials in Jiashao bridge risk probability prediction of risk assessment according to the method of comprehensive safety evaluation of road use;analyse the physical and chemical properties of hazardous materials,use accident scenario method to analyse the possible accident scenarios,use ALOHA software to simulate the consequences of the accident according to the data of Jiashao bridge transportation of hazardous materials and display the impact area of the accident on the satellite map.Describe he transportation of hazardous materials control technology of Jiashao bridge from two aspects of accident risk management and emergency rescue plan which can timely find out all kinds of hidden troubles in the process of road transportation of hazardous materials,to prevent the occurrence of accidents,provide efficient emergency rescue method of hazardous materials accident transportation for JiaShao bridge operation management department.
