Dynamic Stability and Landslide Simulations in Hilly Regions of Kerala
Slope stability and massive soil movement have a significant effect on the hilly regions of Kerala. Unusual heavy rainfall, unscientific construction practices, continuous heavy traffic movement, machine and train-induced vibrations may cause landslides in hilly regions. Soil slopes become unstable due to excess rainfall and worsen under the influence of both rain and dynamic-induced vibrations. Kerala is not known for its seismic history, but the mining explorations at the quarry sites are high. During recent past years, several landslides occurred in the Western Ghats of Kerala due to heavy rainfall. It caused tremendous damage to structures as well as human lives. Hence, it is required to characterize slope stability and provide mitigation methods to prevent failure of soil slopes. The present paper describes the landslide modeling with some case examples of slope failures in Kerala. It is modeled using computer simulation model software called LS Rapid, which integrates the onset and movement of landslides triggered by rainfall, seismic, or both. Initially, the study focused on examining the effect of rainfall intensity on landslides by varying the pore pressure ratios from 0.1 to 1 to visualize the real-time soil mass failure. Further, a slope is subjected to a low seismic time history to represent the influence of minor dynamic loading conditions. The numerical simulations on landslides indicate stable and unstable parts of the slope, velocity, and volume distribution of landslide mass movement after a particular time from the beginning of landslide initiation.
