“…The Karagozian & Case model (i.e., *MAT_CONCRETE_DAMAGE_REL3 or *MAT_72R3 in LS-DYNA) that considers strain hardening, damage, strain softening, and strain rate effect is used to model the concrete of tunnel lining in this study. The accuracy of this material model in simulating the dynamic behaviour of concrete subjected to blast loads has been reported in many previous studies (Chen et al, 2015;Li et al, 2017;Qian et al, 2021a;Qian et al, 2021b). C25 concrete (i.e., concrete with the compressive strength of 25 MPa) is considered in this study, and the basic parameters are listed in Table 1.…”

“…Pilao et al studied the effect of changes in multiple environmental factors on the occurrence of explosions in gas pipelines [14]. Some scholars have studied the combined effects of the area of the explosion, the location of the surrounding facilities, and the orientation of the fire on the utility tunnel [15,16]. Gas leaks are the root cause of both fires and explosions.…”
