| Summary: | The objective of this study is to determine the cause of failure and evaluate the slope stability in order to propose remedial measure for stabilization. The investigate slope discussed in this paper is located at Persiaran Endah and within 10 kilometers from Kuala Lumpur. This slope is around 23 to 28 meter height and approximate 550 to 660. The pertinent engineering properties were analyzed from field test borings which were drilled up to 22 meters depth, seismic refraction survey, inclinometer data, back analysis result, and engineer judgment. Back analysis was carried out to estimate the mobilized shear strength of the problematic layer. SLOPE/W program of Universiti Teknologi Malaysia was used for analysis. Based on the result of the field investigation and numerical analysis the lowest factor of safety (FOS) that evaluated from the existing slope in critical section was found to be 0.741. Therefore, soil nailing was recommended to reinforce the slope, which has an acceptable FOS of 1.525 under static condition. Hence, the installation of soil nailing, grid beam, and drainage were selected for remediation to ensure the long term stability of the failure slope. |
