Investigation of Bearing Capacity of Footings Resting on Sloping Ground

Abstract: Rapid urbanization in the North-Eastern hilly regions, driven by population growth, economic development, and housing shortages, has led to increased construction of residential and commercial buildings on or near slopes. Shallow foundations on slopes have lower bearing capacity compared to flat ground, posing challenges for engineers. Factors like slope excavation, heavy rainfall, and human activities further affect slope stability. This study models soil and structural interactions to analyze slope stability and foundation bearing capacity using software like PLAXIS and ETABS. Results show that larger footings and greater setback distances increase bearing capacity, while steeper slopes reduce it. Ensuring safe foundation design on slopes is crucial for building stability and safety in these regions.
