%X According to general constitutive equation of granular flow,the impact of size fractal distribution on porosity and internal friction angle was studied experimentally by using large-scale indoor relative densitometer and direct shear apparatus.Results show that under conditions of same physical density,same elastic recovery coefficient and same geometric mean median granular size,the porosity increases along with the fractal dimension increasing,meanwhile,the internal friction angle,particle concentration,s...
