Abstract

Study involves the study case of slope failure at FakultiKejuruteraanAlamBina (FKAB), UniversitiKebangsaan Malaysia located in Bangi, Selangor, Malaysia. Slope stability issues have become one of the main problems in construction industry due to the nature of topography and weather conditions in Malaysia. This dissertation examines the stability of the slope of FKAB and eventually to identify whether there have a failure or not using analysis software PLAXIS 2D. The three main objectives of this thesis are, to evaluate the in-situ soil properties at FKAB slope, to evaluate slope stability using PLAXIS 2D and to evaluate the stresses transferred to the piles of the FKAB building. The steps involve in solving the model of the slope were drawn, defined and assigned accordingly before the final analysis is being carried out in consequence to the methodology of the PLAXIS 2D 2008 software. There were 4 layers of soil all together. Layer l with soil parameters of 18 kN/m^3 of unit weight, 90 kPa of cohesion and 20% of angle of friction were assigned. Correspondingly for layer 4, the values of 15 kN/m^3 unit weight above the groundwater table and 18 kN/m^3 below groundwater table, 3 kPa of cohesion and 8% of angle of friction were assigned. In this study, we analyzed that there are some failure at the slope between borehole no 2 and no 3 with total displacement was 35mm. There were no failure occurred to the pile of FKAB building.
