Abstract

Research on the mechanical properties of the modification of the ogee spillway dam with slope variations has been caried out using the finite element method ELMER software. The purposes of this study were to analyze the magnitude of stress, strain and deformation on the ogee spillway. The structure of the dam was modeled with a FreeCAD software, then the calculation of the finite element method with an Elmer software and the analysis used ParaView software. Based on the analysis of the ogee spillway type with slopes of 41.18o, 45o and 48.36o, the maximum stress at the slope of 41.18o occurs in the wall section of the crest spillway in the z axis direction with a value of 2.2 x 105 N/m2, while the maximum stress at the slope of 45o and 48.36o occurs in the base segment of the crest spillway in the xy axis direction with values of 2.5 x 105 N/m2 and 3.0 x 105 N/m2 respectively. The strains that occurs in the three sequential tilt modifications were 35 x 10-8, 47.5 x 10-8, and 65 x 10-8. The deformation occurs in the three sequential modifications of 1.4 x 10-5 m, 1.9 x 10-5 m and 2.6 x 10-5 m. From the analysis of the mechanical properties of the modification of the crest spillway ogee Type it can be concluded that the change in strain and deformation values is greater if the slopes of the crest spillway increases. While, the maximum stress value occurs in the wall and the base segment of the mercu spillway.

Keywords : Finite element method, spillway ogee, stress, strain, deformation.
