ABSTRACT
Ensuring slope stability under heavy rainfall is a critical challenge in geotechnical engineering as it directly affects life and infrastructure. Traditional slope stabilization methods have ecological and economic limitations, making sustainable alternatives necessary. Microbially Induced Calcite Precipitation (MICP) has emerged as an eco-friendly and cost-effective solution for soil stabilization. This study presents a parametric investigation of three slope profiles subjected to varying rainfall intensities, analyzing the impact of MICP treatment on seepage behavior and slope stability. Results indicate a significant increase in the factor of safety post-treatment, demonstrating MICP’s effectiveness in mitigating rainfall-induced landslides. Furthermore, the reduced hydraulic conductivity of bio-treated soil slows water infiltration, preventing rapid saturation and enhancing slope stability. These findings highlight MICP’s potential as a viable alternative for landslide prevention in vulnerable regions. The study provides critical insights into the geotechnical behavior of bio-stabilized soils, paving the way for broader applications in sustainable geotechnical engineering.
