Impact of Groundwater Table Fluctuation on Stability of Jointed Rock Slopes and Landslides

Groundwater level plays an important role in triggering landslides. In this paper, Distinct Element Method is used to investigate the impact of groundwater table fluctuation on stability jointed rock slopes. For purpose, 110 cases including different number joint sets, friction angles, spacings, and angles are considered influence changing a slope investigated through series parametric studies. This study shows that factor safety for slopes can decrease significantly with increasing level, more significant steeper joints. Furthermore, as spacing joints decreases, decreases. However, increases, should rise higher elevation be able have impact. Moreover, similar when high. provides better understanding
