2024-06-26T09:04:55+07:00

The process of forming compression waves acting on structures when exploding in
heterogeneous soil and rock environments is relatively complex. However, with the support of
computers and specialized calculation software, that process will be simulated and calculated more
easily. This article evaluates the behavior of monolithic reinforced concrete structures subjected to
explosive loads in homogeneous clay environments and heterogeneous clay environments mixed with
rubble. There are currently no research or modeling articles on this content. This study uses the material
model of G.R Johnson and T. J. Holmquist [1] to model brittle materials such as concrete and rock, the
Mohr-Coulomb ideal elastic model is used to model the soil environment. . The “Jones-Wilkins-Lee”
equation of state (JWL equation of state) is used to calculate the explosion pressure caused by bombs.
The simulations were performed on ABAQUS 2022 software and used the Coupled Eulerian -
Lagrangian (CEL) method to obtain the results. The research content clearly shows the ability to reduce
the pressure of compression waves on reinforced concrete underground structures when mixed with
crushed rock around the structure during the external leveling process.
