SLOPE STABILITY ANALYSIS CONSIDERING THE PRINCIPLE OF STRENGTH REDUCTION METHOD

Abstract

One of the most important variables affecting slope instability is rainfall. The impact of seepage flow on slope stability is examined in this paper using a strength reduction method. The factor of safety (FOS) for a sandy soil slope is shown to be more affected by seepage flow than other types of soil. The FOS is lower when the pore pressure is produced using a piezometric line than when it is produced using a seepage flow analysis. For slopes with clayey soil, the difference is minimal, whereas for slopes with sandy soil, it is greater and more pronounced. The analysis also demonstrates that installing retaining walls to lengthen the seepage path is effective in preventing slope failure caused by seepage. The analysis also demonstrates that installing retaining walls to extend the seepage channel can effectively stop slope failure brought on by seepage low. This study also looks at the effects of water low on slopes with soil nails, slopes with local loads, and slopes with pile reinforcement. The current study further demonstrates that, for practical reasons, the impact of highly populated soil on seepage flow can be disregarded.
