Abstract

Abstract:

To address the safety management issues of oil depots in case of earthquakes, firstly, seismic resilience is defined as the ability of oil depots to maintain their storage functions in terms of resisting earthquake damage, mitigating secondary disasters, adapting to environments after earthquakes, and quickly recovering after earthquakes. Moreover, an assessment model for the seismic resilience of Oil depot is proposed by quantifying the four types of abilities. Secondly, a quantitative assessment of the seismic resilience of the oil depot is realized through a dynamic Monte Carlo method, considering the uncertainty of the resistance and mitigation stages, thereby obtaining the seismic resilience value. Finally, the performance of the proposed model is validated against the oil depot in an earthquake area. The results indicate that the uncertainty of the resilience ability of the oil depot results in a significant fluctuation in resilience values, and the domino effect has a significant influence on the oil depot's resilience and cannot be ignored. Moreover, the farther the earthquake source distance and the lower the fault slip rate lead to higher seismic resilience. The seismic resilience can be improved by staying away from active faults, predicting earthquake hazards, and reducing emergency response time.
