dc.description.abstractWater in the forms of rain, snowmelt and groundwater is identified to be the major factor influencing the reduction of the stability of the slopes. The increasing trend of annual rainfall has been a major challenge to meet the production requirement in Aruwakkalu limestone mine. The stability of the slopes in active quarry area of the mine under various rainfall intensities is studied in this paper. The slopes are modelled numerically by finite element method and subjected to analysis under strength reduction method semi coupled with transient seepage analysis. The results are expressed in terms of variations in factor of safety, pore water pressure and displacement with different rainfall intensities. Based on the results an economical bench design is recommended to be used when opening a new pit area.en_US
