Stability Analysis of Slopes During Earthquake

On a slope stability analysis as an optimal design process (3)

Abstract

A method for slope stability analysis during earthquakes applicable to the proposed optimal design process is described in this paper.
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.
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.
The stability of a slope is discussed to indicate critical conditions expected to appear as a slip line in this study.
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.
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.
