Parametric and Stability Analysis of Landslide Near Somwarpet, Coorg District, Karnataka
The landslides occur when gravitational force, pore water pressure, and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials. Landslide is one of the most common problems in hilly and mountain areas (which causes transportation problem, repair of the structure, and medical cost due to injuries which are negative economic effect). The study and analysis of slope are essential in understanding their performance and in particular, their stability, reliability, and deformations. The aim of the present study is to analyze the typical slope by varying different soil parameters such as cohesion, angle of internal friction, unit weight, and slope geometry (angle and height). The stability of the slope (factor of safety) is analyzed using SLOPE/W. From the parametric analysis, it is observed that shear parameters (cohesion and angle of internal friction) of soil have a significant effect on the stability of landslides. Unit weight of soil in the landslide zone has less significance on the performance. Also, the present study includes a case study of a failed landslide in Kundalli near Somwarpet, Coorg District, Karnataka. The case study is undertaken to evaluate the key reason for the occurrence of landslides.
