摘      要：Determination of the critical state line(CSL)is important to characterize engineering properties of granular *** size distribution(GSD)has a significant influence on the location of *** influence of particle breakage on the CSL is mainly attributed to the change in GSD due to particle ***,GSD has not been properly considered in modeling the CSL with influence of particle *** study aims to propose a quantitative model to determine the CSL considering the effect of *** hypothesize that the change of critical state void ratio with respect to GSD is caused by the same mechanism that influences of the change of minimum void ratio with respect to ***,the particle packing model for minimum void ratio proposed by Chang et al.(2017)is extended to predict critical state void *** developed model is validated by experimental results of CSLs for several types of granular *** the evolution of GSD due to particle breakage is incorporated into the *** model is further evaluated using the experimental results on rockfill material,which illustrates the applicability of the model in predicting CSL for granular material with particle breakage.
