Abstract

The Buildings at the Mehran University of Engineering and Technology (MUET), Jamshoro, pose a major concern because of the critically low safety conditions. This study analysed the stability of the slopes around Building A and Building B with PLAXIS-2D (Finite Element Modelling Software). The analysis showed that the slopes of Buildings A and B are unstable under natural conditions, with FOS values of 1.099 and 1.002, respectively. Moreover, the slopes were analysed under erosion conditions, and the result showed that on 15° erosion condition, instability increases, reducing FOS to 0.978 and 0.874, respectively. Analysis with building offsets of 0 m, 1 m, and 2 m was also carried out, and it indicated that 0 m offset is most critical. Steep slope angles of 65.7° (Slope A) and 68.2° (Slope B), along with Rocky clay soil of this region, further increase landslide risk, highlighting the adverse influence of slope geometry. Therefore, concrete piles were used as a remedial measure to resist the slope failure. Numerical modelling showed that concrete piles are effective in enhancing slope stability. From the various experimental models, a 1-meter-diameter and 25-meter length (12-meter above crest and 13-meter-long pile embedded at the top of the slope) gave the most promising results. The FOS rose to 2.1 for Building A and 1.8 for Building B, respectively, which reflected a stable slope condition. Piles installed along the slope crest acted as a barrier to lateral soil movement, increasing resistance to sliding forces and thereby reducing the risk of slope failure and potential damage to nearby structures. This approach provides a safe and economic solution. The results of this study indicate that the installation of concrete piles is an effective method for slope stabilization in such geotechnical conditions.
