Impact of seismic coefficient and slope angle on a gravity dam through numerical simulation

A dam is a structure that aids the growth of a country in terms of infrastructure development. For such a magnificent structure design, its stability is vital. The Cheruthoni dam in Kerala, India (gravity dam) was selected for the present study. The reservoir-full condition, hydrostatic pressure, uplift pressure and earthquake pressure forces were chosen for failure analysis by considering seismic coefficient and downstream slope angle as critical parameters. The analysis was done regarding stress and displacement, and the results were interpreted using RS2 software. The results revealed that the downstream slope angle is more critical than the seismic coefficient
