Slope Stability

The document discusses the slope stability analysis of Tezpur using the Swedish slip circle method, detailing calculations for various slices including height, width, volume, and weight. It presents two scenarios with different parameters leading to calculated factor of safety (Fs) values of 1.814272 and 1.574549. Additionally, it includes information on the length of the arc used in the calculations.
