Abstract:
Landslides pose a significant challenge in the northeastern states of India, particularly in Arunachal Pradesh, due to the region's steep topography and heavy monsoon rainfall. This study explores the stabilization of soils of a slope at Bage Tinali, Itanagar of Arunachal Pradesh, using cement as an additive and Polypropylene fiber as reinforcement to enhance the strength and stability. The research emphasizes replacing traditional sand and coarse aggregates with locally available silty soil of a slope to enhance its strength, which proves to be an innovative and cost-effective solution for stabilising the natural soils of a slope. Comprehensive laboratory experiments were performed to evaluate critical parameters, including Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Unconfined Compressive Strength (UCS) and water absorption of the stabilised soil. The results show that incorporating 20% cement and 1.25% polypropylene fiber increases UCS by approximately 1829.48% compared to untreated soil. Additionally, the proposed mixture exhibited notable improvements in MDD and OMC, confirming its effectiveness for slope stabilization in hilly terrains. Economic analysis highlights the cost-efficiency of this method compared to conventional shotcrete techniques. This study offers a sustainable and economical solution for mitigating landslides, contributing to the resilience of critical infrastructure in the region.
