抄録

A method for slope stability analysis during earthquakes applicable to the proposed optimal design process is described in this paper.<BR>The sensitivity of the safety factor is also used here to predict changes in safety in a linearly extrapolated way, and this has been fundamental throughout these studies.<BR>This method can be applied not only to a part of the proposed optimal design process, but also to the dynamic analysis of slopes independently.<BR>The stability of a slope is discussed to indicate critical conditions expected to appear as a slip line in this study.<BR>The distribution of the response acceleration used in this pseudo-static analysis is determined as it corresponds to acceleration and local instability generated in the dynamic state of the slope.<BR>The procedure as well as the results of the application of this method are stated and the estimation of the risk of the slope is taken into consideration.
