Abstract

The design of rock slopes in seismically active areas should consider the risk of earthquake loads. This study involved testing simple models of rock slopes on a hydraulic shaking table and displaying the results on time versus displacement curves. The results were compared with predicted displacements computed using equations available in the literature. At low frequencies and small amplitudes the predicted sliding rates compared very well with the rates observed during the testing. However as the frequencies and amplitudes were increased, the equations overestimated the displacements by gradually increasing amounts.

Physical Modeling to Assess the Dynamic Behavior of Rock Slopes

St. Louis, Missouri

The design of rock slopes in seismically active areas should consider the risk of earthquake loads. This study involved testing simple models of rock slopes on a hydraulic shaking table and displaying the results on time versus displacement curves. The results were compared with predicted displacements computed using equations available in the literature. At low frequencies and small amplitudes the predicted sliding rates compared very well with the rates observed during the testing. However as the frequencies and amplitudes were increased, the equations overestimated the displacements by gradually increasing amounts.
