It can be seen that there is a highly significant negative correlation between the change rate of macropores (△ V _Mac ) and mesopores (△ V _Mes ) and the strength attenuation rate (Δ τ _ f , ) (Pearson coefficient is mostly below − 0.98, Spearman coefficient is -1.000), p < 0.05), Especially when the moisture content increases, the correlation is more significant; However, there is no stable or significant correlation between the change rate of small pores (△ V _Sma ) and micropores (△ V _Mic ) and the strength attenuation rate.
