Investigation of stability and deformation of earthen walls reinforced with geosynthetics under explosion with passive defense approach

Given the sensitive situation of the country and the successive threats, as well as several terrorist acts in the coming years, the need for passive defense is felt at any other time. Therefore, in these cases, the need to protect sensitive resources is essential. Geosynthetics are among the new and efficient materials that, while simple and fast implementation without the need for equipment and specialized people in combination with soil as protective walls, show good performance even compared to time-consuming, costly and time-consuming structures. In this study, the focus is on the deformation of the reinforced earth wall in the face of an explosion. After examining the model by Geostudio / Slope / w geotechnical software in static equilibrium mode, wall deformations were performed by 3D / Abaqus finite element software using MohrColumb behavioral model. The aim of the present study was to investigate the effect of geosynthetics on the deformation of reinforced earth walls against explosion. The results showed that with increasing the distance of the explosion from the wall, the deformations of the wall decrease, but the remarkable point is the rate of this deformation reduction, which increases with increasing the distance of the explosion from the earth wall
