| description | One of the greatest issues regarding Iranian concrete dams is the lack of consideration for increasing our knowledge about them and their performance in times of accidents such as floods, earthquakes, and impact load caused by explosion waves. Some of the most significant objectives of this research are an investigation of the effect of TNT content and its distance from the concrete dam, the identification of critical points of the dam, and the impact of fluid on the amount of damage caused by the explosion to the concrete dam under impact load. The analysis used in this research is straightforward. It should be noted that the discovery of the critical points of the dam in the event of an accident, such as an explosion with complex behavior, can minimize human and financial losses. The LBE method was employed in this study. The interaction between the dam and the water behind it is one of the very considerable parameters that influence the deformation of the dam due to the hydrodynamic pressure of the water behind the dam. It is demonstrated by the results that doubling and tripling the amount of TNT leads to an increase in the pressure on the crest of the full dam by 46.63% and 64.68% respectively; besides, by multiplying the amount of TNT by four and five, the mentioned pressure increases by 70% and 75.58%, respectively. |
