Erratum for “Bounding Surface Model for Rockfill Materials Dependent on Density and Pressure under Triaxial Stress Conditions” by Yang Xiao, Hanlong Liu, Yumin Chen, and Jingshan Jiang

The value of the initial void ratio in Fig. 8 (i.e., $e_0=0.224$) should be rewritten as $e_0=0.224$. Consequently, Fig. 8 in the original paper is redrawn.

The critical state line (CSL) of Tacheng rockfill material (TRM) in the $p^{\prime }-q$ plane is linear, which can be expressed aswhere $p^{\prime }$ = mean effective stress; $q$ = deviatoric stress the model parameter, and $M_{\mathrm{cr}}$ = critical stress ratio.

Therefore, the equation of the CSL in the $p^{\prime }-q$ plane in Fig. 13 should be rewritten as Eq. (1). And, the curve line of the CSL in the $p^{\prime }-q$ plane in Fig. 13 should be replaced as a straight line. Fig. 13 in the original paper is replotted.
