- Description
- Current investigations have shown that earthquakes can trigger significant damages of equipment, infrastructure and environment. This is a persistent cause of economic loss for any country, especially for the loss of life. The conventional method for slope stability design is to utilize limit equilibrium method (LEM) in conjunction with the pseudo-static (PS) approach. However, the LEM has a significant drawback which is to determine the slip surface before factor of safety calculation. The numerical upper and lower bound limit analysis method was employed in this paper can avoid this limitation. In this study, the horizontal seismic coefficient and the slope failure mechanism were evaluated using limit analysis and the results were also compared with the finite difference method.
