A recent experimental study identified a novel "hydro-chemo-mechanical" trigger for soil liquefaction: internal pore-pressure build-up generated by carbon dioxide (CO2) accumulation during the buffering of acidic mine water by carbonate-rich soil. However, the interpretations of the experiment were constrained by heterogeneity and the underestimation of pressure build-up due to system failure following the peak pressure. This study addresses these limitations by developing a numerical framework to quantify the tra...
