Dynamic principal modeling of cemented phosphogypsum stabilized soil under dry and wet cycles.

As can be seen from the figure, under the same bias stress, the dynamic resilience modulus shows an increasing trend with the increase of the circumferential pressure, and this increasing trend is almost linear.

The experimental data were processed by SPSS software to obtain the data results in Table 19 , from which it can be seen that the effects of the number of dry and wet cycles and the perimeter pressure on this dynamic constitutive model are highly significant, and the effect of the consolidation ratio is more significant, the effect of the perimeter pressure > the effect of the number of dry and wet cycles > the effect of the consolidation ratio. 3.2 Dynamic shear modulus-dynamic shear strain structural modeling (1) Influence of envelope pressure The dy
