Research on Compensation Correction of Leak Impact Factor of Kent Index Method

Aiming at the existing defects of pipeline risk assessment model of Kent index method on spill score,population score and leak impact factor, five compensation coefficient are put forward in pipeline risk assessment basic model qualitatively,of which include past failure modes,emergency response, sensitive environment,high value areas and support/oppose of nearby residents.Thus,the compensation correction model on leak impact factor of pipeline risk assessment are established.This model enhances the accuracy for the work of pipeline risk assessment.Finally,the verification analysis showed that the modified model can objectively reflect the degree of pipeline risk.
