SPATIOTEMPORAL SLOPE STABILITY ANALYTICS FOR FAILURE ESTIMATION (SSSAFE): LINKING RADAR DATA TO THE FUNDAMENTAL DYNAMICS OF GRANULAR FAILURE

Spatiotemporal slope stability analytics for failure estimation (SSSAFE): linking radar data to the fundamental dynamics of granular failure

Abstract Impending catastrophic failure of granular earth slopes manifests distinct kinematic patterns in space and time.While risk assessments of slope failure hazards have routinely relied on the monitoring of ground motion, such precursory failure patterns remain poorly understood.A key challenge is the multiplicity of spatiotemporal scales and

Seismic motion input methods of viscous-elastic boundary and numerical simulation of seismic response on large diameter tunnels

To determine the selection of input wave field at the bottom of the viscous-elastic boundary, and study the seismic response of two parallel large-diameter shield tunnels, corresponding numerical models were established for analysis.First, through the study of wave method for seismic motion input of viscous-elastic boundary, several different wave
