For highway systems, these landslides often induce traffic interruptions and heavy economic losses. Therefore, this research project will establish a “Highway slope disaster information collection, integration, simulation, and judgement system”. The system mainly includes three items: (1) Geohazard rapid report system (GeoPORT) for full-time monitoring of slope disasters, (2) Multi-scale geological survey for collecting slope disaster information, and (3) Full-scale 3D simulation for slope disaster inversion analysis (INVERSE-D). Once a slope disaster occurs, the GeoPORT system will rapidly collect and integrate the essential information such as subsidence location, scale, rainfall, and earthquake intensity, and conduct preliminary disaster judgment. Then, a multi-scale geological survey using various techniques is conducted to analyze the possible failure mechanism and to establish a high-precision topographic and geological slope model. Finally, the full-scale three-dimensional slope failure simulation based on the discrete element method is performed to simulate the failure process and to investigate the subsequent impact area of the slope disaster. The results can provide the administration units a rapid reference to reduce the social and economic impacts of disaster.道路邊坡坡地災害速報系統多元尺度地質調查山崩模擬分析Highway slopegeohazard rapid report systemmulti-scale geological surveylandslide simulation
