Slope Stability Analysis at Hilly Areas of Kuala Lumpur, Malaysia

Ismail N. I., Wan Yaacob W. Z., and Ali N. A.

Abstract—Two case studies on landslide investigation were conducted on Kuala Lumpur slope areas. The purposes of the study are to characterise the subsurface conditions, to carry out slope stability analysis and to recommend suitable rectification works. A total of eight seismic refraction survey lines and 13 boreholes were carried out. A computer program ‘SLOPE/W’ was deployed by adopting a limit equilibrium method (LEM) to determine the factor of safety (FOS). The findings showed that the geophysical methods coupled with borehole and slope stability analysis were useful tools for the characterisation of slope failure. The seismic refraction survey results have provided information of weathering and rippability of the bedrock. Based on the analysis, the FOS were less than 1.5 which signify the inherently unstable slopes, thus, suitable remedial measures were proposed to improve the stability of the slope. The application of soil-nail will provide a reinforcing action to the soil mass, thereby increasing the stability of the slope.
