Abstract
In this research, the structural behavior of a morning glory spillway has been evaluated when there is an unbalanced construction in the spillway crest. The unbalanced construction is defned as the ratio of vertical unbalance in construction to the diameter of the spillway crest. The spillway structure has been modeled using fnite element method and the reservoir fuid has been simulated using fnite volume method. The behavior of morning glory spillways with unbalanced crests has been investigated in two scenarios: (a) the crest without any anti-vortex structure, and (b) the crest with anti-vortex structures. Both scenarios have been simulated using dynamic linear analysis method. In addition, in each scenario, three amounts of unbalanced constructions of 0.017, 0.035 and 0.052 have been considered. The analysis results have been compared with the structural response of a symmetric spillway without unbalanced construction. Based on the results, the most critical condition occurs during the water fow over the unbalanced spillway with no anti-vortex structure. On the other hand, the presence of anti-vortex piers causes asymmetric fow on the spillway crest and subsequently asymmetric fow pressure at one side of the piers.
