Determination method for quantitatively distinguishing collapsibility and melt collapsibility of wet melt collapsibility soil under rated pressure

The invention discloses a judgment method for quantitatively distinguishing collapsibility and melt collapse of wet-melt collapse soil under rated pressure. The judgment method comprises the following steps: 1, sampling and preparing a cutting ring undisturbed soil sample; 2, carrying out water immersion consolidation test on different solutions; 3, calculating the additional subsidence of the undisturbed soil sample in unit thickness under rated pressure; 4, quantitatively calculating the melt sinking amount of the undisturbed soil sample under rated pressure in unit thickness by a subtraction method; and 5, judging the collapsibility and melt subsidence dominance under rated pressure. The method is simple in step, high in operability and short in test period, different solutions are adopted for testing undisturbed soil samples to separate collapsibility, then collapsibility and melt collapsibility under rated pressure are quantitatively distinguished, and on the basis, through interval setting of the collap
