RESEARCH ON EARTHQUAKE DISASTER CHAIN MODELS AND HAZARD ASSESSMENT

摘要

The disaster chain theory is proposed to study the development process of complex earthquake disaster. Taken the earthquake disaster of petroleum and gas system as an example, the forming process and the mechanism of the earthquake disaster chain are researched. And three kinds of physical models are established to describe the forming process of the earthquake disaster chain. The schematic drawing of the earthquake disaster chain of petroleum and gas system is given and the possibility of disaster is studied by applying the hazard analysis method. Therefore, this paper provides the new ideas and the methods for earthquake prevention and disaster reduction.
