Abstract:

To prevent landslides hazards, multiple approaches were integrated to develop a framework for detecting and monitoring slope stability and assessing landslides risks along the state highways and roads. In Phase 1, field investigation and laboratory tests were initiated to gain a better understanding of hydrological and mechanical properties of soils or rocks and slope characteristics. LiDAR and InSAR data were employed to detect and characterize landslides. Precipitation as one of major triggering factors is simulated with numerical models and then used in the slope instability analysis. Physical models for slope stability analysis and their applications in risk assessment of landslides were reviewed and summarized to lay a foundation for further analysis in the next phase. At the end an initial assessment of economic impacts of landslides, both direct and indirect costs were included.
