Simulation and Numerical Analysis of the Explosion Effect on the Body of an Earthen Dam in the Injection Gallery

This article focuses on modeling and numerical analysis of the effects of an explosion on the body of an earthen dam in an injection gallery. Earthen dams play an important role in providing water for agriculture, electricity generation, and flood control. However, these dams are exposed to various risks, including explosions that can be caused by military operations and industrial accidents. Even geological activities such as earthquakes occur. An explosion in an earthen dam can have severe and irreparable consequences, including structural damage to the dam, downstream flooding, and even complete dam failure. Therefore, identifying and reducing the risks associated with such incidents is of great importance. _ The researchers in this research aim to investigate the effects of the explosion on the Tezreeq gallery. An earth dam using Abaqus modeling software and numerical analysis with Python. The main goal is to gain a better understanding of the behavior of earthen dams during explosions and provide effective solutions to reduce the associated risks. The problem is defined by presenting the general characteristics of the dam, including its type, the height of the river bed at the dam site, the maximum height of the dam, and other relevant parameters.The details of the construction of the injection gallery, including its length and cross-sectional dimensions, have also been described. In addition, the explosion process and its consequences, such as the rapid release of energy, gas production, and the release of pressure waves, have been explained.
