My research focuses on geo-hazard risk assessment and disaster prevention and mitigation, with particular emphasis on the following areas: Geo-hazard Risk Assessment: I systematically investigate risk identification, analysis, and evaluation methodologies for regional geo-hazards. My work aims to develop multi-scale, multi-factor coupled risk assessment technical frameworks, providing scientific foundations for territorial spatial planning and disaster risk management. Quantitative Vulnerability Assessment of Buildings to Slow-Moving Landslides: I concentrate on the damage mechanisms of slow-moving landslides on buildings, developing quantitative vulnerability assessment methods that integrate physical-mechanical models with statistical approaches. I place particular emphasis on the differential ground deformation of landslides (including differential settlement, differential horizontal displacement, and torsional deformation, etc.) and their non-uniform damage effects on building structures. I establish refined vulnerability curves based on differential ground deformation characteristics, providing key technical support for quantitative landslide risk assessment and loss prediction. Meteorological Risk Early Warning of Geo-hazards: I study the triggering mechanisms and critical rainfall thresholds of rainfall-induced geo-hazards. I develop meteorological risk early warning models based on multi-source meteorological data fusion and machine learning / deep learning algorithms
