Abstract

Cut and fill works around the slopes are common scenes. Hence, slope stability analysis must be carried out in order to assure the slope is safe and prevent the slope failure. In this study, software application approach by GEOSTUDIO 2007 (SLOPE/W) is used for the case study, an under-going secondary school project which is located at Song, Sarawak. A portion of the slope where is being constructed on a cut and fill area has failed. The failed slope is modelled first by using SEEP/W (as parent file) and then, by SLOPE/W, to generate the Factor of Safety (FOS), which is obtained at 0.854. The proposed remedial works are subsequently determined by using sheet piles and soil nails. The obtained FOS is at 1.362 and 1.021 respectively. Therefore, the proposal using sheet piles is more acceptable.
