Abstract

Earthquake-induced slope stability has been evaluated by force-equilibrium of soil mass, although it cannot evaluate how large the deformation will develop and how far the effect reaches down-slope. The present study aims the development of evaluation method for residual displacement of slope during earthquakes by energy approach. We conducted innovative model tests on a shaking table, in which energy balance in a sliding slope is quantified. Based on theoretical considerations on a rigid block model and model test results, a possibility of energy based design for slope displacements during earthquakes has been found.
