| Abstract | ||||
| Failure of slopes usually leads to human and/or environmental disasters. For example, the failure of an earth dam or a riverbank may eradicate villages or even towns, depending on the failure size. Earthquakes propagate from the source fault in the form of waves; these waves induce horizontal and vertical movements which are associated with sudden changes in the vertical, horizontal, principal stresses, and in the generation of excess pore water pressures, leading to failures in soil slopes and dams. Only one earthquake may cause tens of slope failures and landslides cases endangering human beings and structures. Parametric study was performed on a soil embankment in order to assess the response of the slope under the effect of different earthquakes to the geometry of soil slopes, as well as the characteristics of input ground motions. An approach to get the seismic reduction factor for the different slopes under the effect of different earthquakes was developed. The computer program Geo-slope (2007) is used in the analysis. Results showed that just applying the earthquake, even with minor magnitude, causes a significant reduction in the safety factor for the slope, and this reduction rate decreases gradually with increasing the earthquake magnitude. | ||||
