Abstract
Aging characteristics and triggering mechanisms of geological disasters were analyzed to clarify the characteristics of geological disasters in loess areas, develop a geological disaster risk assessment system, and improve risk management of geological disaster. Risk periods of geological disaster were classified on the basis of disaster type, and a time-space coupling mechanism was applied to manage geological disasters dynamically. The risk period analysis was applied to risk assessment of geological disaster in Yaozhou District, Tongchuan City, Shaanxi Province. The risk period analysis may add a new element and promote improvements to practical applications of risk assessment system of geological disaster. According to this research results, new requirements for long-term supervision of farming activities and recommendations for an approval system for construction projects are suggested. In addition, geological disaster insurance product development is proposed.
