Landslide Simulations and Stability Assessment of Puthumala Hill Soil Slope in the Meppady Region of Wayanad in Kerala
Landslides are one of the most destructive natural calamities. During the monsoon season, which occurs twice a year, the Western Ghats, running through Kerala, are prone to landslides. Rainfall is the most common triggering cause of the landslide. Even though there is no evidence of landslides in Kerala triggered by seismic activity, mining explorations and traffic movements also influence landslide occurrence. As a result, the slopes become more adverse and unstable under excessive rainfall and dynamic loads together. The present study focuses on landslide modelling using the LS-Rapid software to examine landslide initiation and progressive movement produced by excess rainfall and seismic time history. It also studied the combined effect of rainfall intensity and seismic time history on the sliding of Puthumala soil slope in the Meppady region of Wayanad district, Kerala. The average pore pressure ratios along the hill are varied in the model to simulate the effect of rainfall intensities. It determines the critical pore pressure ratios that initiate failure situations. Also, stability analysis is carried out on soil slopes using the SLOPE/W software and found soil nailing as a mitigation measure to increase the slope’s stability.
