Abstract
Slope failures on a lifeline such as expressway were observed in Japan Mid Niigata earthquake 2004 and Noto Hanto earthquake 2007. However, it is not realistic to check the seismic performance of component of a lifeline. It is important how to pick up relatively weak section in terms of seismic resistance. In this study, a practical seismic evaluation method of slopes was proposed by reviewing previous studies by the authors. The proposed method enables a rational slope stability assessment of a lifeline.
