On the Analysis and Assessment of Large Concrete Dam Using Finite Element Approach

Abstract

Assessment and evaluation of dam structure are one of the essential components in sustainable hydraulic engineering. Several countries all around the world have given essential attention to evaluating dam structures due to seismic loading and earthquake vulnerability. Hence in the current study, gravity dam failure is studied based on the possibility of overturning or sliding. For this purpose, the potential of the finite element (FE) models is adopted for the analysis using the LUSAS modeler. The modeling procedure was adopted following several protocols of dam design reported in the literature. The modeling procedure was established to have a better understanding of the relationship of crown displacement against the water level concerning the No uplift, uplift-drain effective, and uplift-drain ineffective. The research finding results showed that the maximum deformation in the dam structure foundation with load case 1 at 100 m water level and the displacement in structure foundation with load case 1 at 80 m water level.
