Abstract

The content of the block stone in the cemented filling body is the key factor to determine the bearing capacity.Cemented tailings in uniaxial compression test to be done in the material testing machine of RMT-150C.The experimental results show that the effect of the ballast on the changing law of the filling body in different loading stages.Contrast stress-strain relationship curve,the addition of the ballast is beneficial to increase the compressive strength of the filling body and delayed stress peak.Damage constitutive model and damage evolution equation are obtained by test results.The addition of ballast helps to slow down the growth rate of damage variable and effectively improve the residual bearing capacity through analyzing of the damage variable strain curve.
