Today, in advanced countries, the construction of underground installations, such as tunnels, underground shelters, ammunition and arms armaments, is very important in order to preserve vital and strategic resources of countries Due to the construction of new weapons and penetrating bombs capable of penetrating the depths of the soil and then the explosion. the study of the methods of retrofitting buried structures is very important.in this study, we first study the dynamic modeling of underground explosion load above the tunnel, and then the method of using anchors for hard soils in order to reduce the tunnel deformation and instabilities created in the surrounding soil was investigated and evaluated. In this research, numerical modeling and Plaxis analytical software are used. The results show that the use of anchors in soil stabilization around the tunnel causes a 90% reduction in the amount of high tunnel displacement with constant depth and explosion. .
