Abstract The outburst fragmentation of soil caused by the dissociation of the gas hydrate was studied based on experiments and numerical simulation. The dense discrete particle model (DDPM) combined with the kinetic theory of granular flow (KTGF) was presented to reveal the outburst morphology of soil, considering the interphase forces and frictional effect between soil particles. The numerical simulation results in geometric features are consistent with the high-speed photography results. Moreover, the effects of initial gas pressure and thicknesses of the overlying layer on the occurrence of gas outburst were investigated in the experiments. © 2021 by the International Society of Offshore and Polar Engineers (ISOPE).
