Abstract:

Rock falls on highways while dangerous are unpredictable. Most rock falls are of the raveling type and not conducive to stability calculations, and even the failure mechanisms are not well understood. LIDAR (LIght Detection And Ranging) has been shown to be able to measure the volumes of raveled rock as small as 1cm when repeatedly scanned over a period of 16 months. Rock fall volumes can be correlated to external stimuli such as rainfall, seismic activity, and freeze thaw cycles to determine trigger for failure. A modeling method for raveling rock has been proposed and demonstrated.
