Abstract

This project will learn and focus on the application of FLAC/Slope program to the stability of slopes under the effect of seismic forces. As to analyse slope with seismic force, there will be additional of horizontal force, hence the Pseudo-static approach will be apply to this analysis, where there is a horizontal seismic coefficient, kh will be consider in seismic stability of slope analysis. FLAC/Slope is a mini version the FLAC which was developed by Itasca Consulting Group, Inc. It is a general-purpose program for numerical modelling of geotechnical stability problems. FLAC/Slope is user-friendly computer software and is had been adopted in this project to investigate the stability of slopes under earthquake effects. The current used software is the student version and has the limitation to analyse as only the course mesh can be use to analyse the slope problem. The outcome of the project will be the development of earthquake resistant design charts under constant seismic profile for a variety of slope stability problems. By using the stability number (N) and the pseudo-static approach together with the assistance of FLAC/Slope software, design chart for the seismic coefficient, kh of 0.1, 0.2, 0.3 and 0.4 have been developed. These charts can be useful in the preliminary earthquake resistant design of slopes for determined the Factor of Safety (FOS). To get more understanding of the FLAC/Slope, a parametric study on seismic coefficient and soil properties of slope under the effect of seismic has been done. Also a slope model problem which consist a weak layer under the seismic effect had been analyse by installing geo-reinforcements in various way in order to improve the FOS of the model under the seismic condition.
