specific Embodiment

[0039] Step 1: Get the chemical park data of the road data and the road to be evaluated, and the road data to be evaluated includes road level data, red line width data and road cross-sectional width data, and the parking data of the road includes the location of chemical plant, production equipment and equipment in the park. Data, hazardous chemical storage amount data and dangerous critical amount of data;

[0040] Step 2: First, according to the data obtained in step 1, the major hazard source level of the hazardous chemical is determined, and then evaluate the quantitative risk assessment software for the existing China Safety Production Science Research Institute CASST-QRA Major Hazard Source Region;

[0041] Determining the specific steps of the major hazard source level are:

[0042] (1) Determine to be evaluated;

[0043] (2) Determine the storage amount of a hazardous chemical within the unit and its critical value, and the number of people contained in the range of 500 m...

Abstract

The invention relates to a road grading method based on a fixed major hazard source and application thereof. The grading method comprises the steps: 1, obtaining road data of a to-be-evaluated road and data of a chemical industry park where the road is located; 2, performing explosion simulation on the fixedly stored hazardous chemical substance to obtain death radius data of a dangerous source; 3, obtaining a hazardous chemical substance influence degree index of the to-be-evaluated road and a comprehensive index of facility performance of the to-be-evaluated road; 4, obtaining a hazardous chemical substance influence degree weight W1 of the to-be-evaluated road and a facility performance comprehensive index weight W2 of the to-be-evaluated road; 5, performing weighted summation on the score and the weight of the influence degree and the facility performance to obtain a comprehensive index Z; and 6, obtaining the danger level of the to-be-evaluated road according to the value of the comprehensive index Z and the grading standard. Compared with the prior art, the method has the advantages that the road facility performance level and the influence of a fixed hazard source on the road are comprehensively considered, and road grading is more objective.

Description

Technical field [0001] The present invention relates to road safety or risk analysis level evaluation techniques of urban, park level, and community levels, in particular, involving a road classification method based on fixed major hazard sources and its application. Background technique [0002] The construction of major hazard sources, evaluation, monitoring and emergency rescue system is the core content of urban security, park safety or major industrial enterprises, and the establishment of major hazardous source monitoring systems is the progress of China's major accident prevention technology ideas, "Safe" The first, prevention-based "safety production policy and" gate movement movement, gravity downward "accident prevention measures are particularly reflected. In recent years, there have been frequent issues on the safety accidents of chemical dangerous goods, but most of the research on risk sources is lacking on traffic grading research. When the accident occurs, road tr...
