Inland river dangerous chemical transportation risk assessment system

Abstract

The invention provides an inland river dangerous chemical transportation risk assessment system which comprises an index method risk assessment unit which is used for acquiring accident occurrence frequency data, accident result data and emergency compensation force utility data, calculating a risk assessment value according to the data and obtaining a risk assessment result by combining a risk index grading standard, and a quantitative risk assessment unit which comprises an accident consequence damage quantification module and a risk assessment early warning module and is used for calculating the loss cost according to the domestic cargo passing expansion coefficient, the pollution hazard coefficient and the environmental sensitivity coefficient, and obtaining a risk assessment result incombination with an inland river segmentation result. The inland river dangerous chemical transportation risk assessment system establishes an inland river dangerous chemical transportation risk evaluation system, establishes an accident consequence evaluation model on the basis of inland river environment sensitive conditions, dangerous chemical harmfulness, the most possible leakage rate of a chemical ship and other three aspects, and comprehensively evaluates the accident risk level in combination with accident occurrence probability, emergency measures and other influence factors.

Description

technical field [0001] The present invention relates to the field of transportation, in particular, to a risk assessment system for the transportation of dangerous chemicals in inland rivers. Background technique [0002] In recent years, my country has made full use of foreign safety assessment methods and hazard prevention management experience, and has achieved certain results in oil spill emergency management. However, due to the complexity and special hazards of hazardous The risk assessment of chemical accidents lacks a unified standard, and the risk assessment of shipborne hazardous chemical accidents is still an urgent problem to be solved in the construction of my country's emergency management system. As far as methods and models are concerned, at present domestically, there are mainly several risk assessment methods such as fuzzy mathematical assessment method, gray system method assessment method, analytic hierarchy process and risk matrix method, which can only s...

Problems solved by technology

The chemical assessment model can analyze the concentration change of chemicals after they leak into the water body within a certain period of time, and can also analyze the transformation and distribution behavior of chemicals after they enter the environment, but it cannot reflect the change of the total amount of pollutants over time

The current Analytical Hierarchy Process (AHP) method can assign and score the degree of harm of the polluted objects in the water area. Factors such as the protected area, the species richness of the water area, and the aquaculture area of ​​the polluted object can comprehensively evaluate the level of pollution consequences, and the hazardous chemistry of inland water transport Product risk assessment is shifting from qualitative assessment to quantitative assessment. At present, most of them are index methods, and there are few reports that can truly reflect the consequences of accident pollution to the level of economic losses.
