【摘要】：為了提高對管道事故的認識,更好地預(yù)測和預(yù)防管道事故,歸納整理了事故特征,清晰描述了事故的本質(zhì)特性,提出了一個新的事故評估描述模式,即采用脆弱性、反脆弱性及完整性指標(biāo)量化描述管道發(fā)生事故的狀態(tài)。管道系統(tǒng)的脆弱性是指管道在內(nèi)外部因素發(fā)生變化時可能發(fā)生事故的趨勢,描述的是已知的缺陷發(fā)展為事故或完好的狀態(tài)發(fā)展為事故的可能性;管道的反脆弱性是指在內(nèi)外部環(huán)境因素發(fā)生變化,甚至在發(fā)生事故后,管道的應(yīng)急措施、完整性管理等方面得到加強,反脆弱性表述了管道系統(tǒng)在事故預(yù)防方面向好的方向發(fā)展;管道系統(tǒng)的完整性指管道的物理狀態(tài)完好,耐各種因素變化的能力較強。該模式區(qū)別于傳統(tǒng)的風(fēng)險評估,對事故本質(zhì)的認識和評估更加清晰,并將對風(fēng)險評價技術(shù)方法的改進有一定的指導(dǎo)作用。
[Abstract]:In order to improve the understanding of pipeline accidents and better predict and prevent pipeline accidents, the characteristics of accidents are summarized and sorted out, the essential characteristics of accidents are clearly described, and a new model of accident evaluation and description is put forward, that is, adopting vulnerability. The anti-vulnerability and integrality index quantitatively describes the state of pipeline accidents. The vulnerability of pipeline system refers to the tendency of pipeline accidents when internal and external factors change, and describes the possibility that known defects develop into accidents or intact states develop into accidents. The anti-vulnerability of pipeline means that the internal and external environmental factors change, even after the accident, the emergency measures and integrity management of pipeline are strengthened. The anti-vulnerability indicates that the pipeline system is developing well in the aspect of accident prevention, and the integrity of the pipeline system means that the pipeline is in good physical condition and has a strong ability to withstand the change of various factors. This model is different from the traditional risk assessment, and the recognition and evaluation of the nature of the accident is more clear, and it will be helpful to improve the technical methods of risk assessment.
