Vulnerability assessment method of cities around oil and gas pipelines

Abstract

The invention discloses a vulnerability assessment method of a city around an oil and gas pipeline, which comprises the following steps: firstly, selecting vulnerability assessment indexes from threeaspects of pressure, state and response; Step 2, based on the pressure-responsing PSR model, the vulnerability assessment index system of cities around oil and gas pipelines is established, which includes target layer, criterion layer, element layer and index layer. 3, calculate that weight of each index of the criterion layer, the element lay and each layer in the index layer in the evaluation index system; Step 4, evaluating the vulnerability of the cities around the oil and gas pipeline based on the weight of each index of each layer. The invention carries out vulnerability evaluation on the system through a specific index system, quantitatively processes the evaluation result, and accepts the test of practice, so that the evaluation result is more accurate and reliable, thereby enriching the vulnerability evaluation system of cities around oil and gas pipelines and deepening the theory of urban vulnerability evaluation.

Description

technical field [0001] The invention relates to a vulnerability evaluation method. More specifically, the present invention relates to a method for evaluating the vulnerability of cities around oil and gas pipelines. Background technique [0002] The rapid development of urbanization, population concentration, dense buildings, insufficient safety distance and other safety hazards are all reasons for the frequent occurrence of oil and gas pipeline safety accidents. Due to the complex terrain that the underground pipeline crosses, the high pressure of the conveying medium, and the difficulty of daily detection, the occurrence of oil and gas pipeline accidents is hidden, which is a potential threat to the safety of urban residents. Once the oil and gas pipeline leaks or breaks, it will cause major fire accidents, even explosions, poisoning, environmental pollution and other vicious consequences, especially in densely populated areas, often causing serious casualties and major ...

AI Technical Summary

Problems solved by technology

The risk assessment of oil and gas pipeline systems at home and abroad has roughly gone through the process from pure theoretical research to practical application research. The assessment methods and technical systems are constantly being improved. Most of the research is on the fragility of the long-distance pipeline itself. There are few reports on the vulnerability assessment of cities around oil and gas pipelines
