Abstract

This paper presents the example of landslide triggered by the failure of earth retaining wall. Close examinations such as visual inspections and non-destructive testings revealed that the earth retaining wall does not have enough strength to resist active earth pressure and ground water pressure. This fact is proved to be a direct initiation of landslide. Numerical studies including slope stability analyses and seepage analyses were performed with material properties obtained by geophysical explorations and laboratory tests. The results of numerical studies show that the overturning of the earth retaining wall affects the slope stability, leading to landslide consequently.
