The effect of loading on the stability of rock slopes
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 7
Abstract
The stability of rock slopes is affected by such elements as excavation and loading on the slopes. In order to examine the effect of loading on the stability of slopes, certain slopes withdips of 30, 45, 60 and 75 degrees have been modeled, using Phase 2 software. Then, certain loads of 1, 5, 10, 15 and 75 Mpaon three parts of slopes namely up, middle and down of slopeswere done. Regarding each case, the stability of slopes has been determined by obtaining thestrength reduction factor (SRF). The results obtained from this study have revealed that stability of slopes has been decreased by loading on the slopes and that the effect of loading on various parts of the slope is different. In slopes with low dip, loading on the down part of the slopes has the least effect on instability of the slopes. However, with increasing dip of slopes, loading on the down part of the slopes shall have the most effect in instability of slopes.
