Abstract

In the present study, a finite element technique was used to study the dynamic response of tunnels against underground explosions using finite element software ABAQUS, Explicit Analysis. The reinforced concrete tunnel of 0.8 × 0.8 × 4.0 m size along with the boundary of soils were modelled using FE three dimensional analysis. The inelastic behavior of concrete and steel bar has been incorporated through concrete damage plasticity model and Johnson-cook models available in ABAQUS. The Drucker-Prager model as well as acoustic infinite medium have been used in order to model the damage behavior of soil and tunnel. The simulated results thus obtained from the present study were compared with the experimental results available in literature and found in close agreement. Further, the simulations were carried out on the effect of important parameters such as standoff distance of detonation and mass of TNT in order to predict the damage intensity in tunnel as well as soil strata.
